A little search hack can turn Google search engine into an MP3 ripping demon. You must read Advanced Google Searching for more Information. Copy & paste the following code into your Google search box:
-inurl:(htm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(wma|mp3) "<BANDNAME/SONG>"
Where <BANDNAME/SONG> is either the name of the band you're searching for music for OR the name of the song you're looking for.
