Jim Dalrymple, writing for The Loop, on how Apple Music has started to use fingerprint-based song matching to fix the (annoyingly bad) metadata-based system it was using before:
Apple has been quietly rolling out iTunes Match audio fingerprint to all Apple Music subscribers. Previously Apple was using a less accurate metadata version of iTunes Match on Apple Music, which wouldn’t always match the correct version of a particular song. We’ve all seen the stories of a live version of a song being replaced by a studio version, etc.
I can’t believe this isn’t what the service launched with. The key feature for me has been the combination of my library with a streaming library and every time this fucked up I wanted to randomly delete a line of code from whomever wrote the system so they could feel my pain.
