- morkalork 3y agoMost similar has some hilarious pitfalls too though. I saw a talk by someone who worked on the google play music, or whatever it's called these days, recommendation system and his canonical example was a pure similarity metric would recommend the all-women band "Lez Zepplin" to fans of Led Zeppelin. How's that going to score amongst listeners?
