I never actually counted but thanks to your question I know now. Currently I am enjoying music on 45 playlists and there is zero songs overlapping, with a small exception of “temporary” playlist — where songs are awaiting being sorted and this one is generally a “beautiful mess”.
There might be like 5 songs that occupy different playlists but they are in different versions, covers, unplugged/concert versions or redefining remixes.
I have this neighbor. He is like 70+ yo, after a stroke and a heart attack, barely talks and walks…
Somehow, this guy still has some slapping sense of humor. How come he pulls it off and most people I briefly checked online history of can’t and more often than not are the same people talking “everyone is just too serious nowadays”, “no-one can get a good joke anymore, huh?” or “why they banned me? Again!”…
I am not saying this about OP, but I am starting to notice a trend.
