I think there should be a way to request for more songs, since certain songs I can only find on youtube. I paid for Spotify Premium not youtube premium (too many song copyrights and prefer spotify over youtube for music). I would love to hear unreleased songs that aren't altered or extended for the sake of copyrighting.
Thanks! hope you all feel the same. It sucks not being able to find the quality song you love and saving them on your spotify playlist.

You can also make music request from here Music Request : )
However, adding music on Spotify is almost always a decision by the artists or their labels, so it's not guaranteed that every song can be added.
