No offense Trout but this thread is for reporting problems, correct? You're not helping or adding value here so I will go ahead and look past you. Back on topic, if the Devs have questions about what venue or songs (it's occurred in both Master Mode and Standard Mode), let me know.
But then again, Trout's probably right...it's the Xbox! Although I simply press the Guide button on the controller, Press Y, and exit to the Dashboard. Restart the game, and it loads properly. Nice try, troubleshooter.
