LavaBeat.net is one of the largest online distributors of legal MP3s. They currently offer songs of 44,120 artists and that totals to 159,890 albums with 1,214,560 tracks available for immediate download. The total size of all the available MP3 tracks is a whooping 14.2TB (1TB = 1,000GB). The tracks presented are of all genres from the year 1950 to 2008. 

Their site is very fast and the site design is intuitive. You can easily find the song or an album using the handy browse or search feature. The purchased tracks do not have the copy protection and work well with all standard MP3 players or iPods. The tracks are of the very high quality. Thus you can burn the CDs and play them on any, even the high end, sound equipment.

The prices are quite low - only 15c per track. I think many would be willing to download tracks of great artists. For example, you can download BEYONCE here for just 0.15$.

When you create an account, 15c is instantly deposited into your account as a welcome bonus. This gives you the ability to try their service without actually spending any money; just use the deposited 0.15$ to download a track of your choice.
