I try to keep an open mind...I can enjoy different styles, from Bob Dylan to System of a Down, and everything in between: Old rock (Stones, Doors, Santana), Progressive Rock (Genesis, ELP, Yes), Grunge (Alice in Chains, Soundgarden), Electronic music (Chemical Brothers, Prodigy), Acid Jazz (Medeski), Trip Hop (Portishead, Massive attack), Radiohead (a style of its own), and indies such as Cage the Elephant. Zappa is cool too...As is Neil Young.
I love metal...From Sabbath to Godsmack...I think Korn is a great band... Metallica was good back in the days and Slayer too
Nine Inch Nails is my all time favorite, with The Floyd... I still enjoy those 15 to 25 minutes long musical masterpieces the Floyd crafted in the late sixties-early seventies (such as Echoes...Yes, this means I took a lot of drugs in my twenties :hippie
The only things I can't stand are stupid Gangsta Rap and Country...But then again, Rap can be good and I love Neil Young, even when he goes country
