I really don't know dude.

If I were you i'd just go through them one by one.
but I have lots of time on my hands.

The only thing I can think of is the zune software. you can right click the files and find album info.

also you can select multiple files, and edit them all at once. So if you have all the songs that are in the same album. you can just select them all then change the album info.
