It's very handy: I managed to use it to download the lyrics for almost half of my music collection in one fell swoop.
Except that the author got a "Cease and Desist" letter from Warner/Chappell Music, who seem to think that his program -- which is, basically, nothing more than a specialized web browser -- is somehow in violation of their copyrights.
But, the author doesn't have the time or money to risk a lawsuit, so he panicked and pulled it.
Update 2: Some press (which is almost entirely cut-and-paste rephrasery from Pearworks -- a gem of journalism, really): Music giants bear down on lyric search apps.
Update 3: More press, mostly about the attack on the lyrics sites themselves:
- "The Xerox machine was the big usurper of our potential income," he said. "But now the internet is taking more of a bite out of sheet music and printed music sales so we're taking a more proactive stance."
Update 4: The PearLyrics site now says that Warner/Chappell has "apologized" for the "tone and substance" of their take-down letter. But that means nothing, because the software remains unavailable. Once you can again download PearLyrics from the developer's site, I'll believe that their apology means a damned thing.
Update, 2013: I wrote my own.
