Uh Oh. You've got a copy of you that is three seconds out of phase. Have you been in the same room with an MRI machine when lighting created a power surge? I've only seen this happen once before and, well, I'm not supposed to talk about it. 😎
Seriously, I have no idea what could be causing that pause except a second tap on the play button three seconds into your song. I have another player that will peruse songs by letting you ONLY play three seconds of each in that mode. Is there some scan option set in your player settings?
