On my mp3 player, I've got Pink Floyd (as always :) ), George Benson, Megadeth, Return to Forever, Switchfoot, Albert King, QueensRYCHE (*glares at Earthman's brother*), Iron Maiden, The Third Bend (a friend's band), Wes Montgomery, Voivod, A Perfect Circle, Freddie King, Blue Oyster Cult, Coheed and Cambria, Dick Dale and his Del-Tones, Eric Johnson, Fatboy Slim, Al Jarreau, Hirax, Invertigo, Jimi Hendrix, Lamb of God, Liquid Tension Experiment, Machine Head, the Mahavishnu Orchestra, Metallica, Paul Gilbert, Nine Inch Nails, Peter Pan Speedrock, and a live recording of Jimmy Page, Joe Satriani, Steve Vai, SRV, Eric Johnson and Allan Holdsworth playing "Little Wing".

Shostakovich is on high rotation on my CD player, but I've also been listening to the most recent Shadows Fall album, which is brilliant!

Sorry to answer my own question, btw :o
