Use Google to search and download MP3 files

Basically you could download mp3 files directly from Google search engine if you know how to serve it to Google. To be honest you can actually search whatever filetype you like.
Open up your browser go to Google and enter this text to search box:

• "intitle:index of" "song name and/or band name" mp3

Now Google will search webpages where you entered song name appears. Mostly you get some webpage directory links where its possible to directly download desired song.

We made sample search for Metallica- Enter Sandman song and the results are shown pictures in below.

As you can see Google will show you mostly website directory files where you can directly download whatever you like. Isnt it easy.
