Found this site the other day. Seems like an easy way to find mp3’s on the net. Check out G2P. It creates a string of text and inputs it into a google search field which looks for instances of index pages that include the band name you are looking for.
Assuming that one day this site may not exist, here’s the code.
- intitle:index.of “mp3″ +”band name” -htm -html -php -asp “Last Modified”
