schwa293,
That link doesn't work, gives me a google add. But the Find Album Info is using AMG data and trying to associate information of the CD to AMG data and create a match. It''s not perfect, but the base database is the same as the marketplace, just run by a different team. They also do Windows Media Player and other players as well.
They don't have everything as AMG doesn't list everything as well and because of the way it matches it can make mistakes, which is why it also goes off user information as well, which the Marketplace does not.
That cannot live which eternally lies, and with strange untold eons even death may die.
