Startup Idea : Music service/application

Idea is simple: Application (android, apple, windows desktop) will scan your music library, analyze your favourite bands and music style and return relevant informations like: new album release, missing albums/songs, proposal for new bands, inform you about concerts (maybe also near to you) or even news about the bands. Service can run in form of application (Spotify) news channel (Feedly) or social service (Facebook).
