If you were able to have as many releases as rateyourmusic.com and provide a public API then I'd be very interested. But due to the userbases of sites like rym and discogs who have contributed a lot to the information and number of releases on those sites, it's hard to see how new contenders in this particular space can compete

A public API will be implemented long-term. Releases are all fed from MusicBrainz database (2.6M releases atm), so I'd say that chances that you'll find what you're looking for are high.

And if not, then you can add a release by providing a Spotify/Discogs/Bandcamp/Mixcloud URL in the search box, and it will fetch the proper metadata.
