This one is pretty good too: http://www.dogpile.com

But Webferret is great for coming up with weird stuff that isn't quite what you were after, but takes you places you might want to go to anyway.

And it can get you exactly what you want too - I was trying to find klinks for the words and tune for "Linden Lea" to stick in a post on another thread that's going just now, ("What is a good voice"), and inside a minute I found two sites, one with a midi of the tune, and one with the words.)
