Does anyone know why this would happen again? Basically, I wiped out all of the BIAB songs on my iPod, and then re-transferred them from B2BGo (they were previously rendered, and all of the MP4s are in the folder). However, none of the audio actually transfers to the iPod. I deleted all of the songs again from the iPod and tried again, with the same result - no audio transfers. This is very strange and frustrating. Thank you in advance for your help.
