The first time I tried to add a music or song to my first Youtube video I saw that the video has been uploaded but the song has been disabled due to Copyright problems...I was really frustrated with that..Then I deeply searched on the internet and then finally I found a way to add any music or song to a Youtube video...
Here it is...

First create your video and then add any song or music to it through softwares like MovieMaker,etc...Then upload it on Youtube then carefully follow this...

After uploading your video,open it,you'll see that the music has been disabled..no problem...now Sign in into your Youtube account ,then in your account go to My Videos and then you'll see your all videos...Then in that see your video with the song disabled ,under that video there would be written "View Copyright Info"..Click on that...then a new Web page will appear..In its middle there would be written " I want to learn more about the dispute process",click on that...Then a new page will open ,,,there would be written " Take me to the dispute form"in the bottom right,click on that..

Then on the new page ,,Select the second option and in the box "Please explain briefly"paste this.....

Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use.


Then in Signature block type your name like "John Smith'..

Then in block of "Statement of Good Faith" paste this ......

I have a good faith belief that the material was disabled as a result of a mistake or misidentification, and that I am not intentionally abusing this dispute process.

Then click on 'Continue' and then click on 'Submit Dispute'..

Then check your video and then you'll find that the audio is enabled...
EnJoy...xD
