I've been thinking about this general subject since I first posted in it, and I have some further thoughts... I feel I should differentiate between soundtracks and scores. It was a lesson I learned the hard way when I bought the Batman (1989) soundtrack and got none of the Danny Elfman music I'd been wanting to hear. It was all the songs used in the movie, all by Prince. So very, very not the same thing. *heh*
I love scores and there are certain composers whose work I'd get without hesitation (Jerry Goldsmith, Ennio Moriccone, Vangelis, James Horner, John Williams, Basil Pouledoris...), certain film or TV series whose scores I get as much for completeness as appreciation, and others I'd get when a particular film caught my attention, but I wasn't overly enamored with the composers' other works. But soundtracks... I can credit soundtracks for introducing me to groups or artists I either didn't know about before or had heard of but not listened to (either because I didn't think I'd like them, hadn't liked what I'd heard, or just simply not gotten round to it yet and felt no hurry to do so). Thanks to soundtracks, I came to appreciate or made the effort to acquire works by Jane Siberry, David Bowie, The Cure, Big Pig, Extreme, Scorpion, Bon Jovi, The Machines of Loving Grace, Orbital, and quite a few others.
Sometimes I'm frustrated that a group or artist did a song specifically for a film and the only place one can get it is that film's score/soundtrack, regardless of whether I want the rest of it. The Cure's "Burn", David Bowie's "Real Cool World", U2's "Hold Me, Thrill Me, Kiss Me, Kill Me"... Most famously, Simple Minds' "Don't You (Forget About Me)"...
I gotta say, I was really happy when hard drive space started to get big enough I could rip specific songs (and many of them) uncompressed as .wav files. Happier with where we are now, and I can plunk forty or so albums' worth of music on a 32GB micro-SD card. God, I love living in the future...
