If you want to have the ability to queue songs in the Music application in iOS 8 like you can in iTunes on the Mac, then you need a new jailbreak tweak called UpNext
by iOS developer Hamza Sood.
Shown above, UpNext gives you the ability to choose what music is going to play next whenever you're listening to songs in the iOS 8 music application. It's also fully compatible with iOS 8.1, which is a huge plus, considering Saurik's Cyueue
tweak is not.
