Music loop stutter on inspector

I have placed a 30 second piece of music on a DVDSP menu via its inspector. It runs through perfectly, but when it loops, it starts playing, stops, and then runs all the way through again. How do I get it to loop each time without a false start? Thanks.

I know what a loop is. The point is that it doesn't loop smoothly - It runs, then starts to run again for a few notes but stops, then runs again from the start. The 30 second music track should run to the end, then run again, than again, etc. Not stop a measure or two in and then run again. In other words, the loop stutters, and I can't figure out how to fix it. It is not on a video track but on a menu page.

I fixed it. It was that the exact time of the music needed to be exactly matched on the inspector. When I did that, all was well. Thanks for your time in trying to help me.
