Confusingly enough - no. From what I do [and what I've seen most people do], there's an equal split between listening to:

1) All songs from the movie

2) All songs by the composer(s) (or 'music director')

3) All songs by the singer(s)

...with other edge cases like a specific combination of composer and singer, the decade of movie release, genre or even by the movie director.

ID3 tags and smart playlists are a frickin boon to managing a large set of Indian film music!
