Amie Street is a social networking site that lets you buy music from different artists really cheap. Once you buy the music you'll be able to use it on your Web sites and blogs. Songs are all priced on popularity and can range from a few cents to a few dollars, they're all a little different.

Amazon.com has just invested some money into Amie Street after talks of starting their own online music store. I'd start looking to see if Amie Street will show up in the music section of Amazon.com soon.
