? How to get lyrics into iTunes en masse...?

[videoflyer]

Is there any way to get lyrics into iTunes other than one track at a time? Since the iPhone's firmware these days supports lyrics, it'd be really nice to have them available but all I've found so far (aside from Googling lyrics myself and copy/pasting into the Get Info window in iTunes) is Harmonic which is great for one-at-a-time, as-you-listen fetching of lyrics. But with my library at 16 GB (not even terribly large, eh?) it would take me ages to get lyrics to everything.

Is there an app or script or widget or something that would automate the process of getting lyrics for my entire library?
