I did some Googling. I found this
This takes a mp3 and guesses the song.
I used https://curltoblocks.firebaseapp.com/ to get the blocks from the curl command example
curl https://api.audd.io/
-F url='https://audd.tech/example.mp3'
-F return='apple_music,spotify'
-F api_token='test'
and it uses Kodular colors but it also works in App Inventor.
You will get a json file in return.
