Custom playlists

Hi love you guys and your work. I like the feature that of making playlist based on what you have listen to up in the year's.

Maby I am just being picky about it, but it would have been nice if we could get playlist makers that used what genre u like.

For example; if I like to have a R&B playlist, I then can go over to what R&B songs that I listen to and make a custom playlist using that information
