A steady diet of Metal, Black Metal preferred.
I do like a lot of stuff though and I'm not too picky as long as it doesn't sound generic or deliberately marketable. I really like 70's funk and soul, as well as what they're calling the "Retro Soul Revival" these days and whatever older Shaky Graves is.
But I've also been listening to Sum 41's new album on repeat since I bought it in September and that's pretty solid all around; good album to retire on.
