PearLyrics is a program that displays the lyrics of the currently-playing track in iTunes: it gets the lyrics from the ID3 tag in the MP3 file, or if they aren't in there, it searches for them on a few different web sites, and then saves them into the MP3s.Link (Thanks, JWZ!)
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/Chappel 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.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
