A new iTunes bug has been discovered that causes Apple Music playback issues related to tracks shorter than 60 seconds. MacRumors says it’s able to reproduce the issue on Macs running OS X 10.11.5 and iTunes 12.4.1.
Specifically, when an Apple Music track shorter than 60 seconds is streamed in its entirety, without skipping ahead, the subsequent song in an album or playlist fails to play and appears to be in a state of perpetual buffering, the article says. The bug only affects tracks streamed through Apple Music, with songs and albums that have been stored locally on iTunes unaffected. The issue was unable to be reproduced on a Mac running macOS Sierra beta, nor on an iPhone running iOS 9.3.2, notes MacRumors.
