I like WAY too many bands and types of music to list, but here's something:
I've got a toy that I love, and it's great, no matter what you like to listen to - Sirius Satellite Radio.
The kit comes with two antennas, a car power adapter and an AC adapter. I keep one rig in my car, and then the AC and antenna rig set up at a job I might be on for a while. In the morning, I just pull the receiver out of my truck and plug it in at the job site. Nothing like it - no commercials on the music stations at all, and about 100 different stations that cover every type of music you can imagine. Also, if you can get away with it on a particular job site, they have Howard Stern and comedy stations too - unedited.
As odd as this may sound I prefer no raido at all. Some other people like the darn thing so loud I cant even hear myself think. There is a time and place for music. I consider work not one of them. If its low I tolerate it. For me no music.
