I've been contributing data and code to MB and it's sibling projects for over two years now and the community has been great from day one! Just to name a few of the other projects, there's AcousticBrainz [1] collecting acoustic information which may be pretty useful for machine learning, CritiqueBrainz [2] for collecting user reviews of songs, albums and more, ListenBrainz [3], an open scrobbling service a group of people including former last.fm employees initially hacked together in a weekend, and finally BookBrainz [4], which tries to be what MB is but for books. During the last year the people running MB have worked on getting companies using the data to support the project resulting in a quite impressive list of supporters [5] including big names like Google, Spotify and the BBC. MB has also collaborated with our fellow data nerds over at the Internet Archive to create the Cover Art Archive. [6] In general the project is run by people who equally love both data and hacking. Feel free to stop by on the IRC channels #musicbrainz and #metabrainz on freenode!
