How come Spotify still hasn't a quick way to add a song in the queue? Clicking the song title with the right button, highlighting the "add to queue" and then clicking again looks simple but in fact becomes a lot tedious and not practical at all when creating a quick temporary playlist.
Suggestion: while holding ctrl or other specific key, clicking on the play button doesn't automatically play the music, but instead ADDS it to the queue. I bet many users would like this feature implemented. How about it?
