Death Metal makes up about half of my music library, that's definitely my favorite genre. And about 20-25% of my library is thrash. Those are the two big genres for me. The next biggest for me is probably progressive, then heavy/classic, and then a tiny bit of black metal and grindcore.
I've acquired a taste for more progressive metal bands this year so that genre is starting to get bigger for me.
