This mirrors my own experience exactly. I too listen to a lot of soundtracks, from movies or from video games that I have enjoyed. Although music doesn't provoke an emotional response on its own, it has an incredible ability to being back emotional memories.

For a similar reason, when choosing music to listen to, I generally listen to the same songs again and again - those which have a connection to my past. It is very hard to feel anything about a new piece of music.

This means that I may regularly listen to one track by a particular artist, but have no interest in any of their other songs. I don't even like listening to remixed or live versions of songs that I enjoy - they are sufficiently different that they do not evoke any memories and hence are uninteresting to me.
