It's like a chef baking 300 cakes in 15 ovens.
Really? Wow. I find that I spend a large amount of time cleaning up after bad entries in the CDDB. Likewise, many of my CDs (particularly the obscure-label jazz ones) aren't in CDDB, so I have to type them all in by hand. Plus, I like to get the correct years on every song in a compilation (which you can't do in EAC, so you have to do it after-the-fact with MP3 Tag Studio).
I'm figuring that I could, at best, keep four or five computers going continuously before I'd hit the wall on data entry.
