We want to be able to embed a BrainzPlayer in other websites such as MusicBrainz, AcousticBrainz, etc but also other third-party websites.

The BrainzPlayer should accept listen formats or MBIDs as input and resolve content from the available datasources.

We still need to defined the exact structure of properties that it will accept, but it will accept dicts for each datasource with user info (name, tokens…) and methods to refresh those tokens.
