I'm definitely not able to reproduce this problem at the moment, although I did improve the zooming behavior with text files so that when you zoom and it changes the number of pages, you don't have to restart the zoom gesture. If you can long press your song on the library screen, tap Share->Export as .msf and send it to mike@zubersoft.com, I can try testing with your file to see if that makes any difference. What type of device are you currently using? 

Thanks,
Mike
