Make a separate play list for the sleep music in the year end wrap up

[spanuvf4ezkeke2rre3q]

At the year-end wrap-up, Spotify merges all music into one playlist. However, many users like me, have music we listen to for sleeping and other music we listen to during the day. I believe it would be nice if we had two lists: one for the music we listen to regularly and the artists, and another for the music we like to relax and fall asleep to.

This would make the wrap-up more accurate and improve the algorithm.
