Wish I could help as I'm a big SB user but I turn off all iTunes integration. It was messing up my custom browse scripts used to separate classical music and add sorting by composer, conductor, etc. I point the LMS at the two top level flac and MP3 folders that houses all my music collection and tell it to ignore iTunes. I still get all the same music streamed just without the complication.

Probably a much different situation so I'm just babbling more than helping.
