Yeah I was concerned about the formatting bug, if that is a bug maybe its intended, so will do a backup.

I also heard its transcoding everything ti wma or some odd format is that true? I want to keep my AAC and MP3 files in tact.

I'll still keep hacking away with my song tagging and organization before I worry about the N900 sync process.

Im using Mp3tag to do the brunt of the work but it looks like songbird can do some tag moding too so that may come in handy for the final stage of organizing my music, say I filter by genre and an artist I like has 2 or 3 differnt genre tags by default I would be able to spot that easy in songbird and change them to be all the same.
