Isn’t the whole point of Shazam that you don’t know the song and want to find it? If you don’t know the song, hoeven you provide a Spotify link?

this is a demo of the algorithm, not a full app / hosted service using it with a pre-populated database. The spotify link would be to fingerprint the song and add it to the database
You're right. The Spotify link is used solely to get details about the song. These details are then used to search for and download the song from YouTube. Afterward, the fingerprint for the song is created and added to the database.
The idea is that you add every Spotify song in the database, and then run your match against them.
