Finding MP3's

So, everyday I come across posts all over the net about people asking for a certain MP3 you've just started to get into, or just need one for a friend etc.
What quite a lot of people don't know about is 'Google hacking'
This is simply a term simply to take advantage, filter out and exploit Google in ways other than using as a basic Search engine.

Ok, so on with the fun stuff:
Visit Google and in the search bar type in ?intitle:index.of? mp3 artist-or-song-here
This basically searches through the websites index files for the mp3 you requested, and more often than not, you can find a free, full version of the song you're looking for (excluding rather unknown tracks)

There is also a real neat website that does the same as what I previously posted but don't require you to type all the code in.

There are many different ways to search for files via Google hacking, e.g. searching for passwords, specific text on a website and so on, Just search for Google hacking and see what comes up =)
