My indie is mp3 and ape, and my mainstream is vb ogg
I spend most of my time listening to indie, but I still like classic rock to remind me of my teenage days (late 80's)
Here are my favorite/most listened to
Android Lust(ape/mp3)
Christian Death(mp3/ape)
Gackt (ape)
Black Sabbath (ogg)
Beatles (ogg)
Jimi Hendrix (ogg)
