Playlist recommendation engine?

[snogards99]

I am curious how Spotify recommends new playlists. My playlist is specific to a growing sub-genre of "cali reggae, cali roots, reggae rock, etc." It is by FAR the largest 1000+ songs, most frequently updated (daily) playlist for anything showing up for "cali reggae", however it frequently appears ranked behind smaller or outright 'dead' playlists.

The keyword "cali reggae" appears in the title, description, etc. Is there something I'm doing wrong? Why is my playlist not the top recommendation?

Thanks!

one possible explanation is that the music genre is so wide, that the playlist has a wide spread of Spotify-identified genres (which are often inaccurate). Perhaps the engine can't figure-out what the playlist should rank for?
