Thanks for your help Andrew! I believe I have discovered the AAC file problem...it was occuring only on "frozen" songs. I probably missed that in the instructions...

I still have not found the reason songs with a melody and/or soloist track that I have muted in BIAB, are unmuted in mobile BIAB. I am having to go to the Volume settings in Mobile BIAB and turn them off. It is an effective work around but not what was intended...I don't think.
