AmieStreet, the popular music store, has launched a small redesign and picked up some new partners and music labels, including Amazon.com. The redesign adds a new section for registered members, giving them a personalized home page which tracks recommended songs from friends, new releases from bands, and even attempts to recommend songs you may like based on previous purchases.

Amie Street’s novel approach to pricing also seems to have interested Amazon enough that the company has dropped an undisclosed amount of funding in the Amie Street coffers. Amie Street’s DRM-free MP3 downloads feature a pricing structure unique to the site — all songs start out free and then as demand grows the price increases to a maximum of 98 cents.

The site also rewards savvy users for recommending their favorite songs to their friends. As a song becomes more popular (after a member has recommended it), Amie Street offers members credits toward the purchase of additional songs.

Amazon previously unveiled its own DRM-free download store, but Amie Street’s price structure, and perhaps its new recommendation engine, appear to be too good for Amazon to ignore.

In addition to money from Amazon, Amie Street has some new record label partners. RoyaltyShare, Daptone Records, United For Opportunity and a few others are now offering downloads on the site, which has increased Amie Street’s catalogue ten-fold.
