Have you uploaded a video to YouTube with copywritten music, or no music at all? Maybe you just want to change the music, but have no idea how; or even that it's possible. Well it is, and it's very, very simple!

Go to www.YouTube.com and you'll see a dropdown at the top right that says 'Account'. Click the dropdown and you'll see a list of your videos.

Under the statistics for your particular video, you'll see buttons; Play, Edit, Annotations, Audio Swap, and Insight. Click 'Audio Swap'.

You will come to a screen with several selections of music choices. Select any one that interests you, and click 'Preview' under Step 2 on the right side of the screen. Do this for each of your selected song choices.

When you find a song that you are happy with, click publish. Your current song will be swapped with your new selection. It's that easy!
