It would be useful if you could request data for multiple recordings with only one request, rather than doing N requests.

The use case I'm thinking about is to collect data for all tracks of a release.
So an alternative could be to request by release MBID.

Originally reported by murdos on GitHub (issue #53).

Good idea, but for now we don't have metadata in the server (I don't really want to trust release mbids, as there's no guarantee that they're correct [recording ids either, but that's another discussion])
We were thinking about setting up a slave that could be used for this kind of additional metadata task.

Requesting by release MBID was just a suggestion.

My real need is something like https://acoustid.org/webservice#list_by_mbid in order to create a "MusicBrainz / AcousticBrainz integration" script in a similary way to https://bitbucket.org/acoustid/musicbrainz-acoustid/src/
