How do y'all define 'similar music' anyway. I haven't found the perfect playlist creator or music recommender. Spotify's radio has a pretty low hit rate for me. In some ways, I think there's a market for a multidimensional music similarity search tool or classifier (where playlists are basically classifications).

A few examples. I have a 'rock concert' playlist that maps on style, artist, era/decade, but not tempo (since rock concerts sometimes break up intense songs with less intense ones) and a 'slow lounge' playlist that maps onto instruments, average tempo, tempo variance within song, etc.

What I really want is a way to assign a feel or purpose across a few axes which are not just the typical 'genre'. Something actually objectively measurable like tempo, volume, etc.

Edit: As a side note, I found that country (like Alan Jackson) seems to work better in the car than some other song types. I think it might actually be a frequency thing where country is Darwinism optimized to be audible and enjoyable in old trucks?
