Some factors such as the network environment and access point may cause audio skips. Make sure your network speed/available bandwidth are adequate to the content you're trying to listen to.
In addition to such environmental factors, some specific services are confirmed to cause audio skips when listening to them. Also note that some applications of these services place a heavy load on the unit during playback, causing process delays and audio skips. Please try to listen to another music service and see if the problem persists.
