Sometimes when you look up an album on Amazon, or wherever, for tags and covers your search comes back with multiple hits. Depending on the artist you may come back with 10 versions of one album! And not all those will have track listings or covers.
I wish there were check boxes and sorting capabilities when you get that "list of search results" so you can keep track of the links you click on. Sometimes you check one out and it's not what you need so you go back and well it's a hassle to resort and keep track when realize that wasn't the album info you needed.
Maybe have a "next source" button at the bottom of the "Adjust Tag information" window so you can jump from album to album until you find the one you need. Or a list next to the window so if the first album hit wasn't the one you can select next and so on.
