After a song in your queue plays you cannot go back to it if you want to play it again without going through the process of adding it to the queue again, this can be impossible when you cannot use your phone, such as when you are driving. When you add something to the queue it should be added to the played songs and included in the list of songs when the back button is pressed.

Your idea was submitted a while ago and unfortunately didn't receive the amount of kudos needed to stay active in the ideas board (100 Kudos per year).
In order to keep the Ideas Exchange clearer I'll close this idea for now, but this doesn't mean Spotify rejected this idea.
If you think this is an idea which needs to be implemented, you're welcome to post it in a slightly different form 🙂
Have a nice day!
