I use Play Doctor quite a bit. Oftentimes I will invoke it while listening to a particular song within an album. I’ll be listening and think “this would make a good seed.” Sometimes you just want a vibe to fit your current mood or whatever.
As you know, if you choose “Play with doctor” the list will be built but the song will start over. I would love it if I could invoke Play Doctor on a song without that song starting anew.
