I never used these much, Jay had a good starred list that I listen to a couple times
The search is slow and doesn't send the full string, but sends it in pieces so the response isn't always fresh. ie typing "queens of the ston" will return "queen", but won't return "queens of the stone age" until you edit the search string, I was finding myself always removing a letter and adding it again just to refine the search. Is my typing too fast for Spotify?
