I'm a music fan. If its good then I'll listen doesn't matter the genre. But some of my favorites:
-metal: all types from black sabbath to tool to cradle of filth to as I lay dying
-rock: 60s 70s some 80s and 90s alternative, most new rock I wouldn't put into the genre of rock
-folk/folk rock: Doc Watson, Mississippi John hurt, Peter Paul and Mary, Kat Stevens, and man more
-Delta Blues: Blind Lemon, John Lee Hooker, and Muddy Waters
Alt Americana: Jay Munly
Americana/ Country: Johnny Cash
Orchestral: mostly movie pieces especially those composed by John Williams, but I also like other composers and arrangers like Frank Ticheli and Gustav Holst and Franz Beibl

I could go on and on about all the music I like but I leave you with these: Hymn to the Fallen http://www.youtube.com/watch?v=m6m4C-JrYus Stack O Lee http://www.youtube.com/watch?v=HlniDmj10u8 Denver Boot
