Hi all.. In my task to fix up all my uploaded and matched songs in iTunes, because thanks to meta-data being wrong, what actually causes this NOT to match ? eg, if one track/song has incorrect meta data in one field (eg incorrect artists) will this be enough to throw of Match and report as "Unknown" ? even though yes it may be in the store, but the fact one of the track was incorrect match "thinks" the album is not correct? in addition when actually matching up the meta data and finding the track in the store to get info from so you can fill the required fields in, does it matter where the song comes from ? I mean the same song/version say of 'Britney Spears - Opps.. i did it again'" may be on several albums..... When this is the case, which one do you go for ? This is probably 99% of the time.
