I took all my 100s of CDs and saved them to my music. Then I put them on my iPod and added some songs I didn't have CDs for through iTunes. I love my iPod and put it on shuffle. If you have the steering wheel controls you can advance the songs if you are not in the mood for a particular one. Otherwise, if you don't want it to shuffle it goes through alphabetically. I do have a CD in there, just in case I'm in the mood for a certain artist. Just got to get into the 21st century....
