Pandora should easily be able to create a "Queue" showing upcoming and previously played songs on Auto-Play, similar to Spotify.
Moderator Edit: Edited title for clarity
@rramos17 The track that is in your queue will not play while you are listening to a station.
Additionally, if you are listening to a playlist, the song in your queue will not play until your entire playlist is cycled through. Meaning, every track that is on your playlist has to play before it moves on to what you have in your queue.
Hope this helps clarify.
Provide a queue when using Pandora Premium on desktop. Desktop version only allows instant play of a song or requires creating/adding to a playlist. I have no desire to create a playlist. I simply have some songs that, at that time, I wanted to hear play at some point during my workday. I honestly can't think of a reason why this feature wouldn't be standard across all platforms.
