Many YouTube users create an original video using their favorite song as the audio in the background. They won't be able to do that any more, since YouTube has started muting any videos that use unauthorized copyrighted music. You will see a message at the bottom of the video that says "Notice This video contains an audio track that has not been authorized by all copyright holders. The audio has been disabled. More about copyright"
But how far does this go? What if I capture a home video with my CD player playing music in the background with my 2.5 year old daughter dancing to it? Will YouTube "silence" the audio leaving my daughter dancing in eerie silence?
I think copyright holders need to get a grip in the digital age. Besides, people don't go to YouTube to listen to music for free. They go for the fun & entertaining videos. By removing the YouTube user's artistic license and replacing it with silence I feel as though my 1st Amendment right to "freedom of speech" has been silenced. Where's the ACLU when you need them?
