Sounds like you enabled Tools > Options > Auto-Organize and have a bad Mask. Disable this or change the Mask to have a full Path (ie. C:\Music\<Album Artist>\<Album>\<Track#>. <Artist> - <Title>).

I'm getting this and it's rearranging my whole hard drive repeatedly - I've now got a real mess of folders with an ever-growing path of artist\album\artist\album\artist\album\artist\album etc - each time I turn MMW on it seems to add an extra sub-folder. Any suggestions?

Thanks--this'll be fixed in the next MMW build (note that it's just a presentation issue).

Yes

Does the duplication persist if you disconnect and connect the device again?

If I open the song information in MMA then it's displayed correctly.

How about in MMA?

I detected that after I sync from MMW to MMA the artist and album artist are duplicated. This happens only for songs which have more than one genre.
If there are 5 genre then the artist and album artist are duplicated five times. If there are 7 genres then it get duplicated 7 times.

I have attached some screen shots here: [url]http://imgur.com/a/x8jQA[/url]

Is this a bug?
