Use Google to find free music

This is less design-related and more an interesting way to use a Google Search to find open music collections online. Put the following code into a Google Search, but substitute your favorite band name for "Tortoise":

-inurl:(htm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(wma|mp3) "Tortoise"

The search should yield a listing of open directories containing mp3 files.
