Is this happening on any one or two specific tracks? This is a known bug if it is, some corrupt MP3s hang for a couple seconds before going on to the next one in the playlist. Empeg has said this bug will be fixed when the new decoder is implemeted with v1.1. The best fix is the rerip the affected tracks.
