Google Code-in

Find a non-single release that doesn't already exist in MusicBrainz (make sure it's one you have legal access to).

Then you should do the following things:

• (Optional, if it's a CD you have:) Rip the CD using a good CD ripper, e.g., EAC on Windows (also runs under Wine on Linux), XLD on Mac OS X, or whipper on Linux.
• Add it to MusicBrainz - be sure to enter all information you know/can find, including status, release date and country (country will likely be "[Worldwide]" for most digital releases), label and cat. no. and barcode (these may not be available for digital releases), language and script information, type(s), and packaging ("None" for digital releases).
• Use MusicBrainz Picard to tag the release.
• Use Picard to submit AcoustIDs for the files.
• Download one of the AcousticBrainz clients and submit AcousticBrainz analyses for the files.

Post a link to the release you added here in the task when you've added it so the mentors can verify your work.

If you have any questions along the way, you should join #musicbrainz, the IRC channel for MusicBrainz editors. Even if a mentor isn't around to help you, there are plenty of other people with years and years of experience editing MusicBrainz who are willing to help newbies. Be sure to mention that you're from GCI. :)
