I feel a bit stupid for having to ask this, but I just cannot find the solution on my own …
My problem is this:
Often in my cue of songs already played there is a sequence I would like to repeat and I do not find any way to accomplish this.
I am looking for something like " Play from here".
That exists, right? But where?
Thanks for any help!
In the Queue screen “Scroll up to see previously queued items”
Tap a song above the “now Playing” line to play
Thanks, Jeff!
That was easy … 
My problem was, that I always tried to click the picture (and not the text) and that brought me to the track’s details.
