This has been such an interesting thread - I love hearing that I'm not the only one with song lyric sheets in the car with me (Thanks, Joe) learning songs as I drive around Baltimore and Wash D.C. (in my case, from a tape I make called "songs to learn"). After a conservation with another friend who sings in her car a lot, we thought there might be a market for bumper stickers that say :

"This may look like a car
But to me it's a concert hall"

As for needing written lyrics, I have so little free time that although I probably could listen to a CD and scribble, I'd rather be singing, so if someone else has already done the scribbling part, I'm more than willing to take advantage of it.
