Do I need an API key?

No! MusicBrainz is completely free and open. No authentication required. Just subscribe and start searching. Rate limit is 1 request per second.

MBID stands for MusicBrainz Identifier — a unique UUID assigned to every entity in the database (artists, releases, recordings, labels, works). Use search tools to find MBIDs, then use get_* tools with the MBID for detailed info.

What's the difference between a release and a release group?

A release is a specific physical or digital version of an album (e.g. the 2012 remastered CD). A release group groups all versions of the same album together (e.g. "The Dark Side of the Moon" as a canonical work). Use release groups for finding the canonical album.
