Two days, a room full of hackers and one theme: music. This is the premise behind the Stockholm Music Hack Day, which resulted in 31 projects including hardware hacks, mobile, web and desktop applications. A number of the web applications are live and available for anyone to use.
discoverOmatic allows you to discover new artists and tracks while listening to the radio or even your own collection. Simply select the radio station you're currently listening to (currently on BBC brands supported) and we'll do the rest.
Mystery Music Search gives you the results for whatever the person before you searched for. Heavily inspired by mysterygoogle.com, and using the new Echonest search_tracks api.
A live feed covered the event, including a number of photos, twitter posts and video feeds.
