Locust Toybox anyone? If you've seen "Salad Fingers", you're already familiar with Locust Toybox, if indirectly. These days I mostly listen to ambient, post-rock, all kinds of anime, film and game OSTs including ones that seemingly no one else listens to (Limbo, Machinarium, Yume Nikki, Diablo, Rosenkreuzstilette, Amnesia, A Clockwork Orange, Kikujiro, Amelie, Clint Mansell's score in Moon, even The Book of Eli, along with the staples like FF7 and what have you), and "experimental" stuff like Boards of Canada, Utabi and Aphex Twin, especially his earlier works. My musical tastes are VERY eclectic. I've been sort of "drifting away" from aggressive music, i.e. hard trance and metal, though I could never bring myself to hate metal.

If you haven't heard of anything I've listed, I implore to you to do some research. About the only type of music I don't listen to and can't quite appreciate is anything wildly popular at present. Lady Gaga, Katy Perry, Kesha (or "Ke$ha" apparently), Justin Bieber, Kanye West, 50 Cent, and so on. I always get a chuckle when I hear any of them claim inspiration from Queen or David Bowie or whatever. I'm also a bit irked at the assumption many people seem to make that music only counts if it: A)is marketed by a label/played on the radio, and B)contains lyrics that they understand. Music is whatever you make it out to be. If you assume music has to be in 4/4, can only use the same 4 chords for every song, and must have lyrics about either dancing or falling in love, then that's just what music will be to you. I guess my point is that there isn't anything inherently wrong with liking music from a game, it just happens to be commonplace on the Escapist because it's a site about gaming.
Sorry, that was tl;dr. Paragraphs would have been nice. I admit, I'm a bit pretentious when it comes to music. But at least I'm fairly well-versed, I'd think. :\
This is a site dedicated to covering video game-related topics however. Most threads are pretty random anyway. "Do you prefer ketchup or mustard?" kind of random. It's a bit of a lost cause to seek out music appreciation around here, unless you specifically go out of your way to evoke it. It'd be like complaining about a lack of game-love, or game OST-love, on a music forum. I do think more discussion should be had about music and how wonderful it is, but judging by my musical tastes, I'm probably not the person you'd want to get the ball rolling with.
