My Favorite keeps flipping/swapping in and out from Metal and Psytrance.
One minute Metal, the next, Psytrance. I CAN'T TELL ANYMORE!! Dx
But in all seriousness, I think I need to re-post my answer.
I really should have just put: Metal, and a lot of different sub-categories of Electronica.
Because I really like Dubstep, Drum n' Bass, Psytrance, and well, a lot of stuff... But I can't stay on just one.
It's a constant battle between Psytrance and Metal. xD
But as of this moment: ...well, I think I've been listening to Metal more as of most recently. But that may change back to Psytrance at any time.
