I just got off the phone with a Motorola technician. I learned that my Droid 4 stock music player does not allow the option to repeat a single song. He confirmed with me that Motorola apparently removed this functionality despite the fact that its predecessor devices (D1, D2, D3) all had that feature. I know the easiest thing to do is the use a 3rd party app but I prefer the stock media player because of the ability to control the player from the Screen Lock. Apparently there were only 2 reports of this incident so escalating to Motorola for their next fix might not take priority. It's such a basic feature on all music players that I feel this is very poor design by Motorola.
Has anyone else experienced this issue? I hope there could be enough threads to escalate for the next fix.
