Alright listen up, you are meeting someone for the first time or carpooling or you met a friend of a friend and how do you get to know them best? Through their music taste. In fact, you really want to be jamming out with them but you just don’t know what songs they like and you really don’t want that awkward silence when you know a song and they’re like.........uh......... I don’t know the words. What’s the solution you ask? A friendship playlist. You would find your friend on spotify and there would be a button next to their name that says “friendship playlist” which would automatically create a collaborative playlist consisting of all the songs you have both put on your playlists, 100% guaranteed bangin’ time while you both sing along to the songs that you both know!
I can´t imagine the outcome of this function and I don´t think that i would use it, but if it existed would be ok.
