Feature description:
In the example I will post, the player app has the ability to show the amount of time to play all the songs in that playlist. Certainly not a necessary addition, but kinda cool to see how long it would take to play through that entire playlist.
Problem solved:
Wouldn’t solve any issue at all, just a nicety. 
Brought benefits:
Just show more details about your library
Other application solutions:
PlayerPro and Rocket Player both can do this, and it works very well.
I’ll circle in this screenshot what I am trying to relay to you…
