Hey Jeffrey! I haven't heard anyone else with this problem so I think it may be at your end. However, if you could tell me a specific song and show you're having problems with I can check my file and make sure nothing went wrong on my upload.
If you're using xAct, I am guessing you have a mac which unfortunately I know little about. Trader's Little Helper is a great free program but only for Windows. I was searching to see if it was compatible with mac and found this list of alternatives. Maybe one of those could work?
