Just seen this on Sky News: Help Us Test New Music Site: Mflow | music recommend friend technology unplugged | Technology Unplugged | Sky News Blogs
A, at the moment, semi-interesting app that may one day rival iTunes and Spotify. The idea is you 'follow' friends, artists, etc Twitter style and they recommend new music. Friends can also follow you and you can recommend new music to them.
Maybe a bit more interesting when it leaves beta testing and adds a few (ok - alot) more music.
