XD It's not as hard as you think.
I mean, we tend to gravitate around people with similar tastes, so most of my mates are metal-heads or classical music fanatics. Which means, so long as the radio isn't on, or I'm not over at some strangers house (It happens ^__^ don't ask) Then I hear no pop at all.
I do indeed... Well.. To be more precise, I play just about every instrument AND sing, all horrifically ^__^ - I'm more of a composer than a performer, I play most instruments just a little to get an idea of how to use them well in a piece better. XD It's kinda odd, because rather than learning to play (or sing) well, I learn ALL the possible ways to play that instrument/sing, so I can sing, scream, growl, Yodel, Chant, Throat-sing, Harmonic Sing, Pig-squeal, etc, but I'm not actually great at any of them. I can hold a tune, and that's about it lol.
