I normally listen to whatever pops up next on the iPod. Mostly heavier 80-90s rock, with a tiny bit of newer country. Linkin Park, Hinder, Seether, Metallica, Motley Crue, Brad Paisley and Trace Adkins.
But I've had the gandkid with me quite a bit lately and he likes sing along music and the only kid friendly stuff I have on the Ipod is Christmas music left over from when I was in charge of music for the last holiday pot luck at work. So that is what I've been listening to lately on the way to work. I've had the Chipmunks and Rudolph stuck in my head for a week.
