Spotify - Quick Add to Playlist behaviour (First shot 🤗 )

I have been wanting to post something here for a while.
I did this on my bus ride home, as I was adding songs to my playlists.
I wish Spotify did it that way :)

This was done in 30 min and I am missing couple of things:
- pressed state on the plus button
- playlist cells should react to drag over
- playlist should scroll when dragging to bottom of the screen.

Please feedback and rebound!
