Add music to top of playlist

[TheTrashman030]

As of right now it isn’t possible to add music to the top of playlist in custom mode. The closest thing to this is to sort by recently added, however with the recent mixing features, it’s become more difficult to listen to recently added music while using this feature. Having an option to add music to the top, or even copy playlist order to reset the custom numbering, would allow us to use the new mixing feature with recently added music.
