I've got a late library of music I'm trying to import back from a rather silly mp3 player that has all the music on it untagged and named so:
track1.mp3
track2.mp3
track3.mp3
and so on...
with each bunch of tracks in a folder entitled
artistname album name
so for example apex twins album spyro would be:
aphex twin spiro/track1.mp3
aphex twin spiro/track2.mp3
I see that you can select a few files and put in the artistname album name into a freedb search and seemly come back with a fairly reliable match, which then updates the missing tag data (very cool)...but can I do the whole shebang at once....there are 1000s of albums and doing it one by ones gonna take me days... 
Yours hopefully
Ben
