and Google corrupts absolutely. With that maxim in mind, this little Google hack might be of interest:
-inurl:(htm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(wma|mp3) "Linkin Park"
Of course, you can replace “Linkin Park” with whatever other artist or work you may be interested in. This searches open web folder indexes for files that people have uploaded and left publicly accessible. Other enterprising folks have even built an entire application around this, called G2P (Google to Person).
Please use your newfound powers for good, and not for evil.
