I know what "schlager" is, in fact, in Latvia we have šlāgermūzika (schlagermusic) or šlāgeri - about the same, only in latvian. Well, i'm not really into that, but I thought i'd just point out the fact.. :)
Doom and stoner metal/hard rock stuff mainly, like orange goblin and black label society, crowbar, down, corrosion of conformity, pantera, damageplan and rebel meets rebel. love singing johnny cash in the pub when im pissed tho!
I'm mostly into all punk, including ska and crust, but i still stay with my first musical love METAL. All metal like Cannibal Corpse, Cephalic Carnage, All Shall Perish, Vital Remains, Unearth, Dimmu Borgir, Mayhem, etc. along with that I do get in the occasional rap, alt. and classical.
