While WinAmp does what you need play MP3s its competitors add features like the ability to organize music, record songs from audio CDs and copy MP3s to portable devices.
MusicMatch Is Best MP3 Jukebox Software
For all the portable MP3 players and MP3-playing
stereo components, I still mostly play MP3s on
my computer. I've been using WinAmp on my PC
and MacAmp on my Macintosh since I started
listening to MP3s, but with all the other choices
out there I thought it was time to see what I was
missing. After checking around I'm convinced now
that MusicMatch is the best MP3 jukebox you
can download.
