Looking for a good Music Database API

Hello everyone, I am working on an app that entails users searching and choosing any song of their choice, so I was wondering if anyone knew any good music database API's I could use? I seen Spotifys API has some pretty bad rate limits. For context, I do intend to release this app on the app store, so in the best case scenario the app could take off and have loads of users, although that's highly likely not to happen 😂 thanks for any help! <!-- SC_ON
