Good news: I've found the crash bug on started the included songs. I had a bad build, and I did a clean build now, and all of the songs play. I'll post tonight.
Still crashes at the end of the song though occasionally, and never gets to the high score screen for now. It'll get there. I blame my MP3 library glue code for some of the issues. It seems a little flakey. I have some better glue code that I'll add later this week if it works better.
