I use a tool called Tag&Rename for (hense the name) taging and renaming audiofiles. There is an option in this program, to lookup IDtags from the Amazon database.
From this database you can retrieve tracknumber, title, album notes etc etc etc.. and coverart (will be saved as folder.jpg and it will be saved within the tag). I am using this function mainly for the folder.jpg.
There is only one but in here... it also saves URL information on where to get this album. I used to delete this info with Tag&Rename.
There is NO info left, when I check the properties in Windows Explorer, so this is good.
Now when I open the same mp3 in Foobar, it still gives the URL information when I check the properties.

How is this possible? Is Foobar using "deleted" data?
