Tune Up will automatically fix all of your tags, but I don't know how well it does with the genres. Going song by song would probably work the best. iTunes, and I'm sure a lot of other programs, will let you modify tags on multiple tracks at once. A lot of people seem to like Winamp, but I've never really used it so I don't know if it would work for what you're wanting to do.
I'd like to do this! Can I request an actual CD, though? I'll burn you one too, of course. I don't have a last.fm, but here is my Pandora profile to give you a general idea. PM me if you [or anyone else] want to exchange :]
I hope someone else makes you one too because mine is really mellow and solemn all the way through. Use the m3u file because it is essential that you listen in order. <3
