Most of the big media players like 'windows media player' and 'Itunes' will attempt to automatically tag and organise your files. Twice i've let them do that, and all i can say is "NEVER AGAIN!!!!"
First time was 'Itunes', i let it organise 60gb of music, and what did it do?..... If an album was a compilation of different artists, it put every track in it's own individual folder! Then worse still, any track that it didn't know what it was went into a folder called 'unknown artist'! This folder had over 600 tracks in it! comprising of 50 odd 'Track 1's 50 odd 'track 2's... etc...etc. It was horrible! and took quite a while to sort back out. I uninstalled the horrid program after that.
Second time wasn't quite so bad but it still got me miffed! i let windows media player loose on my music collection, and it tried to attach the appropriate artwork to the mp3 files. Now i had a lot of the artwork but it wasn't attached, it was in the folder with the album, and most media players will recognise this, and display it when you play the album.
Windows media player proceeded to download artwork off the internet and attach it to the files,disregarding the artwork already there, problem was that it was terrible quality, and wasn't always the right artwork. I'ld uninstall that if i could
It was sorting that out when i discovered MP3tag
glad it helped!
