You want me to upload the tracks from my device?
The problem is clear: MMA is copying the artist tag to album artist, for example:
I have in MMW a file that has this properties:
Artist: Jarrett - Peacock - DeJohnette
Album Artist: Keith Jarrett
In the Media Tree in MMW i see this files under Album Artist > Keith Jarrett. So that´s ok.
but after syncing, in MMA i see them under Album Artist > Jarrett - Peacock - DeJohnette, and if i go to properties for those files, "Album Artist" has been changed to Jarrett - Peacock - DeJohnette, copying the Arist Tag, and the same with other files, so I get this in my Album Artist view: (where i should have one entry only)
