Hi, Pops can occur if the level at the end of a loop is vastly different from the level at the beginning of the loop. Try to start/stop a look at a low point in the way (although not always possible). I am working on 11.2.5 and am not noting any pronounced popping during play/pauses. After an upgrade it sometimes helps to kill all your apps and do a restart of the device. Is it all songs? Are other apps running? Tap the Title bar to reveal Tune info and have a look at Music Settings, Try resetting them. If we can reproduce the problem we may be able to find a solution.
