I have horribly banal tastes, but I don't mind.
Maybe I don't have the eclectic quality for appreciation that more intellectual types would, but my music tastes are the one place where I feel no shame nor guilt over it (although I do in every other aspect, such as math, technology, and politics...)
I tend to pick up a good amount of random indie/rock (leaning more towards the mainstream end, as opposed to the folk end) from playlists that a few people compile.
I don't have much loyalty to any specific acts (aside from long dead or retired ones like Frank Zappa or King Crimson).
These days, though, what I'm really looking to find more of are two specific genres that can be tough to wade through. 80s Funk, and 80s New Wave (leaning somewhat more towards the Synthpop end of New Wave than the Post-Punk end).
