This is by far the largest music metadata database that is publicly available. For comparison, we have 256 million tracks, while others have 50-150 million. Our data is well-annotated: MusicBrainz has 5 million unique ISRCs, while our database has 186 million.

Does this mean the MusicBrainz database will soon go from 5 million to 186 million tracks?

My cat would hate this because the footing is so uncertain.

Have you tried the box it came in?
