Spotify tracks cannot be added to My Collection?

get the following error when dragging from spotify to my collection, is this seriously by design?

Hi @audiosymmetry, yes, Spotify tracks can only be used within the Spotify source in djay. They aren’t able to be added to My Collection playlists. This approach is part of how Spotify provides their catalog for DJ use, and we’re glad to now support it directly in djay so you can access and mix your Premium playlists on desktop. You can, however, add Spotify songs to the djay Queue. Thanks!
