Would be glad to find some help regarding this behavior.
Here are the steps to replicate:
1. Select a few tracks and add them to the Now Playing queue by selecting "Play Now"
2. Select track that's not in the Now Playing queue by single left clicking on it
3. Play and click the FF icon / skip track
MB then keeps alternating between the selected track and one of the Now Playing tracks.
To add to the weirdness, when MB plays the selected track, it shows as another track playing in the Now Playing panel.
As soon as I remove the selection, Now Playing returns to expected behavior.
What have I done? Any way to fix this behavior?
EDIT: found it again a few minutes after posting.
For those who are wondering: Edit -> Preferences -> Now Playing -> Untick "playback follows cursor"
