Maestro: Social Music Streaming
Maestro lets you stream music from your computer across the web, for easy listening anywhere. This is a lot like what music locker services Oboe, MediaMaster, and Orb are doing with a social networking twist. Not only can you stream music from your own computer using Maestro, but you can also stream music from your friends on the network (Oboe lets you share channels with friends, but through email links). They plan on expanding to other types of media in the future.
But if your music server is off, don’t worry, because you can listen to music off your friend’s computers. Their playlists show up along with yours on your playlist page or from within an embeddable player widget like the one on the co-founder’s MySpace page. However, streaming from your friends may put an unnecessary strain on their bandwidth. I imagine some bandwidth rules will be implemented to prevent abuse. If their computer is offline too, you can still see what music they have and what their most recently played tracks were. Since they haven’t implemented any social music recommendation, these recently played lists are all you have to go on for finding new music.
Maestro is looking for funding and is currently testing amongst a small group in private beta. You can apply for an account on their site.
