htaccess Rerwite rules colliding - apache

Question

I have to rewrite rules that collide with each other. Actually, it's the second rule that causes the first not to work, even when I switch positions.
artistmusic.php
From: http://www.example.com/artistmusic?slug=Ben
To: http://www.example.com/Ben/music
artistvideos.php
From: http://www.example.com/artistvideos?slug=Ben
To: http://www.example.com/Ben/videos
Rewrite rule for the above urls.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)/([^/]*)$ /artist$2?address=$1 [L]
This works like it should, until I add the rewrite rule for the set of URls below.
allsongs.php
From: http://www.example.com/allsongs?standard=popular&request=monthly
To: http://www.example.com/songs/popular/monthly
allartists.php
From: http://www.example.com/allartists?standard=popular&request=monthly
To: http://www.example.com/artists/popular/monthly
Rewrite rule for the second set above.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)/([^/]*)/([^/]*)$ /all$1?standard=$2&request=$3
The rule above works but kills the first one.
What is the cause of this? Thanks.

With your shown samples/attempts, please have your htaccess rules file in following manner. Please make sure to clear your browser cache before testing your URLs.
RewriteEngine ON
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^songs/([^/]*)/([^/]*)/?$ allsongs.php?standard=$1&request=$2 [NC,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^artists/([^/]*)/([^/]*)/?$ allartists.php?standard=$1&request=$2 [NC,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/(music|videos)/?$ artist$2.php?slug=$1 [QSA,NC,L]
Generic solution: In case you don't want to hard code values in your new rules then try following. Make sure use either above OR following only 1 at a time.
RewriteEngine ON
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/?$ all$1.php?standard=$2&request=$3 [QSA,NC,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/([^/]*)/?$ artist$2.php?slug=$1 [QSA,NC,L]
