Ive always wondered why there is only 1 shazam. I was under the impression the algorithm/patent was just licensed from another company. Why havent people cloned this app? Also why arent the shazam geo charts more detailed ie by city/neighborhood or location. Would love to see what songs djs are playing at a location even if im not there. Right now the geo charts are very high level (only major cities)
The actual audio fingerprinting/music identification project associated with MusicBrainz is AcoustID (https://acoustid.org/). It's a separate project that happens to be well integrated with MusicBrainz.
