Well, I use MusicMatch to make my playlist, and most of the time I use it to listen to my music. For some reason, I haven't figured out, it sounds better. I have SBLive, and you would think all music players would sound the same. I also have DFX on all the players, but MusicMatch still sounds better. I like Winamp 5 next best, mostly for the visulazations. iTunes is real close to MusicMatch, sound wise, also playlist wise. It's easy to make a playest with it. I haven't used WMP 10 very much, but it does have a fairly good sound. Another ons is 1by1. Not popular, but it is a nice little player. I've tried every player on the net. MusicMatch seems to have the best sound. QCD is an excellent player, but right now I have a new computer, and don't have it downloaded. By the way, I'm a musician . Have been for 35 years, so I think I have a little knowledge on sound and players. I also have Bose speakers. 'nough said. Peace. Hippie
