I like pretty much all music - from the usual pop and rock to classical, via techno, drum and bass, 'easy listening', punk, etc. The only stuff that doesn't really do it for me (though there are exceptions) is modern R'n'B type stuff, Reggae, and Jazz.
I haven't bought a CD for years, as I download my music. The last mp3 I downloaded were 'Umbrella' by Manic Street Preachers (cover of the Rihanna song from last summer).
The 'music' folder on my PC currently stands at around 10,000 mp3 files, and is about 30Gb!!
Last 5 tracks I listened to (with iTunes on random) were:
PFM - 'Danny's Song' (dreamy, light drum and bass)
Sugar - 'Hoover Dam' (from the excellent 'Copper Blue' album from approx 92)
Doves - 'Pounding' (a truly epic anthem)
OMD - 'Tesla Girls' ("No, no, no!")
Kraftwerk - 'Radioactivity' (makes me feel very nostalgic, for some reason!)
