My tastes are pretty much all over the place.
Most of my music collection is 70's and 80's era Punk Rock with more than a handful of 90's era stuff.
(Iggy and the Stooges, The Stranglers, The Clash, The Ramones, Dead Kennedys, NOFX Naked Aggression, Angelic Upstarts, Crass, Sloppy Seconds etc.)
I also have a significant collection of 1st, 2nd and 3rd wave Ska.
(Prince Buster, The Skatalites, The Specials, Madness, Selecter, Kongo Shock, The Mighty Mighty Bosstones etc.)
The rest of it is a mish-mash of genres and eras. Looking at the stack of CDs on my desk right now I've got Bruce Springsteen, Metallica, Stevie Wonder, The Andrews Sisters, Rob Zombie, Gorillaz, Billie Holiday, Gnarls Barkley and Patsy Cline.
It's actually pretty difficult to find a genre of music that I won't listen to and enjoy to some degree.
