In my car right now...
Disturbed, Linkin Park, a dance mix CD, a regge mix CD, Incubus, and INXS (that damn "want to be a lead singer for INXS" show has me listening to that oldie-but-goodie. I can't remember the name of the show).

In my office "entertainment system" right now...
Rober Miles, Everything but the Girl, Enigma, Josh Groben, Massive Attack, and an R&B mix tape.
