Well, my tastes have changed over the last eight years or so, but they still basically remain in a couple of genres. I am increasingly listening to classical music, I like acoustic/folky stuff, electronic chill-out music and concept stuff like Pink Floyd.
I have recently developed a liking for Billy Bragg mainly because of his work in prisons, and his views on social justice. I listen to a fair bit of Matt Redmann, Delirious, U2, Donovan, Bob Dylan, Bruce Springsteen, The Clash, Manic Street Preachers, Paul Weller, and Radiohead amongst others.
