Thanks for the suggestion! Yes, I tried different music (in mp3 format) and it still got stuck. I also tried suggestions from an earlier post (to Arrange all points, to start over, etc) with no luck. I finally came up with a workable solution for this case. I ended up adding in the same song 4 times and clicking on "play songs in random order." However, initially I had wanted to use two different pieces of music. I had to scrap that idea because I just couldn't get it to play without freezing at the end of a song. (And the random order option wasn't applicable for timing reasons. I wanted to sync slides to spots in the music, hard to do when you don't know which song will be playing). So I'm still looking for suggestions or a solution for this problem for future projects. Thanks!
