After matching and uploading I have 2 out of 6,250 tracks with iCloud Status as "Error". The tracks seem fine to me. After seeing this I right-clicked the tracks and selected "Add to iCloud". I still got Error after this. Both of these tracks are part of separate albums and all other tracks on their respective albums matched/uploaded fine. The first is "Plush" from Stone Temple Pilots "Core" album at 192kbps. The second is "Werewolf, Baby! (Las Noches del Hombre Lobo Remix)" from Rob Zombie's "Hellbilly Deluxe 2" album at 320kbps. Anybody else see this or know what causes it?
