I am obsessed with my Sirius XM radio. It's usually on Cosmo Radio (Wake Up with Taylor is my absolute favorite) or 90s on 9, and Radio Margaritaville for the Buffett Buffet.

It depends on what mood I'm in. Mostly Hip Hop/Rap to and from work. Old school and new school.

Mostly/mainly jazz flavors, Christian music/traditional and jazz. I also really enjoy classical music.

ETA: When I'm at work, the designers are allowed to listen to music via iPod etc. I listen to only Classical music at work. It helps me with my ideas and designs. I've always sketched while listening to Classical music.

Q102, a local top-40 radio station. I like to listen to upbeat music while I drive. I also sometimes play a Pandora station from my phone, usually Bon Iver or Mumford and Sons. I want to start listening to books on tape though. My commute is 45 minutes each way and sometimes I drive there and back twice in a day (so 3 hours of driving total). Books on tape would probably be a better way to spend my time, haha.
