We are looking to develop a web application which would allow users to play songs via Spotify API by tweeting in their song choices.
Since the internet connection can not be relied upon, in order to do this, we are hoping to cache ALL the track information locally and only connecting when songs need playing.
Now, how feasible would this be if we were to do this via the API or can we somehow have a single data dump?

This isn't really possible, since 1) there's no API to get everything in the Spotify catalogue, 2) that is a LOT of metadata - it'd be impractical to download and store it all locally, and 3) doing so would be against the Spotify API ToS anyway.
and only connecting when songs need playing
If you need to connect to the internet to play anyway, performing the API call to get track metadata shouldn't pose a problem.

I am trying to get a list of music services to which the Sonos household has a subscription. Is it possible to obtain such information from HTTP API or from any other source? If yes, then under what conditions?
I have analyzed the traffic between the Sonos Connect and Windows Sonos Controller. I discover, that information about music services is transmitted from Connect to Controller inside the ThirdPartyMediaServersX tag of the NOTIFY HTTP request. But this content is encoded in the base64-like cipher.

I expect to obtain list of music services, but the actual list were hidden.
As you figured out, Sonos disabled this functionality some time ago.
I've spend a lot of time figuring out how it works, and I now have a "work-a-round". External music services describes what to do.
And sonos-ts has support for external music services. If you read my first link and check the code in this library you should probably be able to figure out how to do that in your programming language.
I know this is no access to the list that is kept by Sonos, but this work-a-round also saves the tokens on the device for every client application to use.
Recently I've found someone who build an music service emulator. So that are both sides of external music services.
This is not supported by the Sonos API.
I'm integrating the Sonos Control API into an iOS app. In our app:
the user is signed in either to Apple Music or Spotify via an Apple Music subscription or a Spotify premium account.
the user can play Apple Music and Spotify content within our app (we have the track / album IDs and use this to play music via the Spotiy / Apple Music APIs).
the user also has the Sonos app installed, and is logged in to their music service of choice (Spotify or Apple Music).
Now when the user is listening to a track in our app, we'd like the user to be able to listen to it via their Sonos device. Our app is for children and has parental control, so the user needs to stay within in our app.
Is there currently any way to achieve this?
Options we've looked into:
Streaming: As I understand it, there is no way to stream audio to a Sonos device. The AirPlay-Sonos compatibility is not an option as we're targeting all Sonos devices.
Sonos Control API: We then looked into starting the track using the Spotify or Apple Music track ID via the Sonos Control API, but this answer seems to imply that this is not possible. Is this true even if the user is logged in to the Spotify / Apple Music service both in our app and in the Sonos app? For example I could imagine using createSession with a Spotify / Apple Music accountID so that I would have access to these services, and then using loadCloudQueue to load the trackIDs. But I could be misunderstanding the API.
sonos-objc: This looked promising, but is very outdated and we haven't managed to set it up.
Any leads on this would be greatly appreciated.
Thanks!
You are correct, streaming tracks directly to Sonos is not currently supported in our platform. Using music object ids, with their constituent content and account ids, is a vehicle for actual content partners to build direct control integrations with Sonos. iHeart, Pandora, and Tidal have done this for instance.
The reason non-content owners can't utilize this functionality is due to the way authentication is handled. To ensure rights-holders property remains intact, we require partners to execute an account matching flow. This account matching requires direct access to a content partners' auth back end, pretty much limiting these types on integrations to the content partners themselves.
We understand that non-content partners want to put content directly on Sonos, and we're actively looking for the best ways to do that, while still allowing content parters to maintain control of how their content is consumed.
Is there any way to use an API to control playback on my registered spotify connect devices? I'm not trying to create or add a new connect devices but control playback to them.
Is there any official or reverse engineering discussion on how to do this?
As far as I can tell, there is no way to do this currently.
That said, it's also unclear if or when this feature will be added. Spotify hasn't updated its api code in months. It also appears that the login functionality is broken on my app too. Spotify doesn't seem to be easy to work with.
Scenario: Spotify user on the native desktop application is adding and removing songs from the currently playing playlist.
I'm curious if it's possible for me to detect when any addition/removal happens? Basically need a trigger to tell me the playlist has changed without having to continuously poll Spotify's API to see if anything changed. Looking for a solution that could be used either via the Spotify API or something hack-ish using spotilocal or listening on Spotify's 4070 port.

I wouldn't recommend this approach since the mentioned APIs may change without notice. It's not publicly supported so there's no commitment from Spotify to avoid breaking changes. It also requires the user to have the Spotify desktop application installed.
As you've noticed, since there's currently no way to subscribe to changes in a playlist, e.g. by a Websocket or HTTP PubSub interface like PubSubHubbub, your application would be forced to poll for changes. If you go down this path, I strongly recommend that you make use of the ETags and snapshot_id provided in the Playlist response.
Declaring how ETags are implemented in the Web API deserves a longer response and should be on the developer site. There's however a useful Working With Playlists guide on there that explains snapshots and some other things related to playlists.
It's also worth mentioning that all applications are rate limited, so I urge anyone polling to be aware of this and poll less rather than more. Obviously only poll when the application is actively used by the user, and only poll the playlist if it's actively viewed. You know you're being rate limited if you retrieve a 429 Too Many Requests response.
I am asking this here because Soundcloud does not have support. I going to build a website that people can purchase audio files from using Soundcloud to download the files (and stream before buy). I want to be able to access the download file link in the Soundcloud API without the download link being enabled and showing on the Soundcloud UI. I can't seem to find this info in the Soundcloud API docs. I am going to have a Paypal redirect after the payment to the download link. I know this is a weird way of doing this but I have certain criteria I have to meet. I would host the audio files on my server but they are huge. Anyone have experience with this or can help?
im not sure its possible to do what you want. (very easily at least)
there would be no way for the purchaser to access the 'download' track on soundcloud directly unless downloads are specifically enabled for that track.
really the only way to not host the files and still be able to provide the download would be to use the api to download or proxy the track from soundcloud to your server, using your credentials (because you always have access to your own tracks, download or stream). mind you this would use 2x the bandwidth usage (the server getting the track from soundcloud, and the client downloading the track), and storage space would only be impacked on a temporary bases. but. this is a pretty hacky way and not really a good/proper solution.
you can:
-compress/re-encode the audio as to not use as much disk space
-pay for more storage space at your web host, its usually pretty cheap thse days.
So you want to charge on something free? Well, I think all the downloader out there are middleware where they stream the track from soundcloud and response to client as attachment upon request, one of many examples is http://wittysound.com. Cheapest way to get thing done is providing direct link to soundcloud server like what http://soundflush.com does
