The songs will play great for 4 or 5, then start to pause, it could be once a song, or multiple times a song. it can last anywhere from 1 sec to 30 seconds. If i replay the song, it will not skip in the same place. I have uninstalled, deleted cache, deleted updates, deleted files on my sd card and my internal. I have moved the app from SD to internal.  reinstalled several times. It doesnt seem to want to play straight through a song.
*It does it with head phones, no head phones
*screen locked/or unlocked
*Apps running/no apps running
*Wifi or 4G
*streaming/ or downloaded
*internal memory/ SD card
basically it doesnt matter, its going to skip.
