Renaming MP3 Files/Tags

[Clarkey]

I've got quite a few gigs of music files. They are all full albums. The problem is that the tags on some of the albums mp3's are wrong so itunes won't pick them up and then some of the ones that it does pick up are not sorted correctly on my ipod due to the album, artist, and song number being out of whack.

How can I change all of this stuff easily? I am ok with manually going through them file by file but only if there is a spreadsheet-esque program that allows me to easily change stuff.

I've found a few programs but it's too hard to click file by file, or for example, to just change the album title for all files in a folder.

Does anybody have any solutions?

I've heard of, but never used, MusicBrainz Picard.

I'm trying it out right now. It scans the audio, and gets a fingerprint of the track. Then it does an online lookup to try and identify the track. It will then sort your tracks into albums, and tag them properly with the data from the database.

Pretty much, I think this is "it".
