So i am still having this problem, however now, whatevers in the now playing list it will just go between the top 2 in the list. in program or out of program the global keys Fast forward or Back just rotate between the two.
when i let it just finish the song, without intervention, it will still just alternate between the 2.
I believe the new version may have botched the playback, cause I never had this problem before i updated.
this is the keyboard keys, the actual player buttons on the interface as well. it will not cycle the whole playlist, just the top 2
