The scoop on MP3ShakeMP3 Shake looks unfinished as a music download site. Compare it to sites like MP3va and MP3Million and it leaves a lot to be desired. The half completed design aside and the site isn't up to the job as well as others. Songs are each, which admittedly is a lot cheaper than places like iTunes, but when MP3va offer songs for a lot less, you can see why others sites are better than MP3 Shake.
The sites charts are very out-of-date and they offer just over songs to download. If we compare this to another site, MP3 Mixx, who offer over 3,000,000 tracks, MP3 Shake really has got a lot of improvements to make before it can be considered as an alternative to iTunes or as your regular music download site.
