MP3Mixx is a great site, packed with loads of handy features.

This includes world top albums, bestseller albums, new mp3 addons, UK charts, US charts, Europe charts, world charts and popular charts.

The site is very cheap too, songs are 15 cents each, the minimum top up on the site is $20.00 and they offer over 3,000,000 mp3 tracks to browse and download. That's a lot of music.
