Why on earth didn't Apple build this kind of thing into iTunes? If you ever wanted to sing along to your songs in iTunes it's a must-have.

It's simple, reasonably attractive and customisable. If I was being fussy I would say that the lyrics tend to look a bit squashed up against the top of the window – an extra bit of space at the top (and at the bottom when the lyrics are long, or you have the artist/title displaying) wouldn't go astray.

I'm using it along with the 'Get Lyrical' app, which finds lyrics from the Internet and automatically adds them to iTunes. The combination of these two programs, 'Get Lyrical' and 'Cover Version' is a nice solution.
