IT's a WhaT?!

This is quite easy.

When you have a host, it will give you 3 essential things:

FTP Server
FTP Username
FTP Password

Secondly: Download Filezilla Client and enter the 3 things above and for the last box put in 21 for FTP uploading.

Thirdly: Upload your music file in the server, and remember where you put it.

Fourthly:
