Find which of your playlists you've put a song in

[delysid23]

I've got close to 3000 "liked" songs in my Library, which I've put into a couple hundred playlists.

But there is no way to find out which playlist I've put a given song into, except by manually opening each playlist and looking for the song.

This is ridiculous.  That's the kind of repetitive tedious task that computers were made for!  

Please let us right-click on a song to see which of our playlists (if any) that song is in.

P.S.  I see this suggestion has already been put into Spotify's "Closed Ideas" pile, way back in 2012.  They say they carefully considered it and then decided not to.  They don't give any reason, however, and I am at a loss as to what the reasons could be.  This idea suggestion should be reopened and reconsidered.

WHO'S WITH ME?
