Maybe cohen was asking for the version ?
I know it happens to me with 11 a lot.
I can rename an audio file to the name i want and when the player connects to the net it automatically changes the album art, the artist and whatsoever.
But the real filename itself does not change, only in MP that it displays as something else.
This has to be in settings somewhere.
go to tools-->options, then the privacy tab.
Un-tick "update music files by retrieving media from the internet".
It has sometimes proven to work
hope it helps mate
