If someone doesn’t know what Shazam is, it listens to music playing on the radio or TV and identifies it and helps you find the name/artist.
I was wondering if there open source equivalent, I tried searching google and AlternativeTo but only found Linux desktop apps.
[CW: Uninformed copyright law speculation] IANAL, but a hash of music is not the music itself, something that can be converted to music, or in any way protected by copyright AFAIK. That being said, I think the rest of your comment is correct.
I’d agree about the database probably not being copyright, but I was more talking about getting access to the music to convert in the first place.
