Input:
I've had a Compaq MP3 player for over a year, and needed more memory, as my wife and I use it at the gym, and get tired of the same songs, and having to constantly re-download new ones. But when pricing more memory, I found this one.  Can't beat this...the Sony can hold 4 times as much music than my 64mb player, and the best part is I can easily change mindiscs for even more variety. Each one holds about 80 songs in lp4, with the quality just as good as my mp3 player.  I've had for 3 weeks, and everything is great--downloading, play, and sound--and I still haven't changed the one AA battery!
