options to look up INDIVIDUAL SONG TITLES when searching for a good playlist to purchase

SOMETIMES I hear a song (or artist) and i really WANT TO BUY THE PLAYLIST THAT PLAYS THIS SONG.. OR SEE IF THE SONG IS IN MORE THAN JUST THAT ONE PLAYLIST.. BUT I CANT LOOK IT UP BY SONG.. ALL I CAN DO IS LOOK IT UP BY PLAYLIST..(ESP IF I FORGOT 2 SAVE THE SONG BY HITTING THE ♡HEART "saved song" BUTTON).. BUT EVEN THEN, IT SAVES THE SONG, YES, BUT IT STILL DOES NOT TELL ME WHICH PLAYLISTS I COULD FIND THE SONG INCLUDED IN... i have no way to locate or pinpoint which playlist contains the song even after they are saved...

So in the search bar where u are able to search for diff playlists, I want it to also find individual songs I'm trying to find... so I want to type in the name of a song I'm looking for, and have it show up underneath in the list that falls down of songs that are the exact match... and allow me to click on it and select it.. and bring me to a list of any/all playlists in which that song is included in!!!

If I type the song, and nothing shows up it will say no match found, and that will ,mean the song does not exist on this game in any playlist and hasn't been added yet, then it will give me an option to request it to the team/mangment.

But if, in fact, it DOES SHOW UP on the list... .. it will show up on a list of song links...& when i click on the link i want, it will then take me to whatever playlist/(S) that song is found in... kah-peesh??? Thanks alot song peeps. MUCH LOVE

AND SOMETIMES I LIKE A SONG OR SINGER AND WANT TO SEE WHAT PLAYLISTS CONTAIN THOSE SONGS .... 

THE ONLY WAY TO KNOW IS TO GO TO DIFF PLAYLISTS ONE BY ONE AND HIT SONGS AND AEE IF THE SONG IS ON THE SONGLIST FOR EACH PLAYLIST BUT THAT WOULD TAKE YEAES TO FIND.... AND IT MIGHT NOT EVEN BE IN ANY PLAYLIST AT ALL . HOW FRUSTRATING WOULD THAT BE RIGHT
