As a user, I love anywhere.fm but as an investor, I'd have a qestion about its legality because of the UMG vs MP3.com case. http://en.wikipedia.org/wiki/UMG_v._MP3.com Have you guys looked into that? Seems to me that these two services are almost identical and anywhere.fm has an excellent frontend.
Excellent question! The most precise case to follow is the MyPlay case. In fact, the ex-ceo of MP3.com created a startup, similar to ours, that is protected under the results of the MyPlay case, which showed that digital locker services are kosher. In fact a quick google search shows you this space has many competitors :).
