It's right in front of you but you have to know what your looking for.
Let me explain. There are hundreds of hosting sites out there, many hosting mp3 files. Now i'm sure some of you have seen this before but may not have clicked on. When you type a song name into Google, 9 times out of 10 it will auto-complete with the word 'zippyshare' at the end.
This is because of the vast amount of people searching for the same thing.
Zippy Share is a file hosting service from which you can preview and download mp3 files.
Get where i'm going with this?
Search for your file and type 'zippyshare' at the end to locate that file within the hosting site. Try this out with other file hosting sites if you cannot find what you want.
Again, if the file is not free to download I will not be held responsible for your actions.
