I just went to wal-mart and got a creative labs Zen Nano. Excellent mp3 player for 53$ 250 songs and 18 hours on a AAA. lil tunes for the bike is nice

 

Creative Labs makes a nice player. I bought the bigger brother, the Zen. Holds 15,000 songs, and plays off a 15 hour, rechargible lithim 3.7 volt battery (same as most cell phones). My jacket has a pocket for this type of thing, and I run the wires inside the jacket and into the helmet. I only wear 1 clip-on earphone.

Make sure you put toghether a nice playlist for the bike. I have several, depending on what mood I'm in, but there is nothing like opening up the throttle, or hitting the curves, to a great tune. Really gets the blood/adrenaline flowing.

 

I just bought one of these a few weeks ago. It's awesome so far. So much better than another I returned for terrible menus.

 

One of my friends bought the Zen. He really likes it. I am still using my 3rd generation(old school) IPod. I am a loyal Apple user and could go no other way!!
