We're currently in the BETA stage of launching MusicDirectx - partnership with Jazzpromo.com - a site that served over 3 millions mp3 downloads over 6 years.
MusicDirectx is part of the RDX Media Group which includes Radiodirectx & MusicDirectx.

DOWNLOADING MP3s
1. Click on an artist name
2. Look on the Left Column Menu for "Music"
3. Click on "Music" and all songs will be displayed - look for the red "MP3" button and click to download.

That's it. Very straight forward.
