Global search through all of my playlists at least in Desktop App

This idea is related to the problem of playlists (and not knowing which of them contain the specific track) mentioned by several other members.

So, the big problem for me is that I have more than 60 playlists now and if i want to find all the tracks that I have by one specific artist, for example, I need to go manually through all of my playlists that might include that artist and search inside each one.

The idea is to implement global search that finds all the matches from all of my playlists with possibility to play them all at once as well. It would be hugely helpful and time-saving.
