> Every recommendation engine I've encountered appear to be based on the idea that I care about artists or genres, rather than the sound profile of individual tracks. And sometimes I don't even know why I like a particular song. This is especially true when it comes to the concept of catchiness. There is certainly some music theory around hooks, chord loops, etc. but I honestly haven't found any of it anywhere near as explanatory or predictive as more well-established classical western music theory concepts like harmonic function or voice leading. So often it really just feels like "that song is super catchy just because it is."
