I create playlists for almost all of my music. I play music as background 24x7. It would be nice to be able to create a “master” playlist then add other playlists (not the contents of that playlist) to this master. Part of the reason for this tiered approach is the shuffle limitations. Once created, I would queue the master playlist and playback would then open each sub-playlist one at a time and play the contents of that playlist. I can add and remove as many playlists as I want while each playback of an individual playlist is shuffled separately. Enabling the Repeat functionality with the master playlist would result in non-stop playing of months or years worth of music.
I tend to manage my music at the album level only and within my own created genre groups.
