What's the procedure in adding copyrighted music to an uploaded YouTube video?
We've been creating some original video that uses some copyrighted background music. But when we uploaded it to YouTube, it gets blocked due to copyright claims.
There must be a process to correctly add such copyrighted background music, because we can see many videos doing this. Examples:
Note that these videos have an iTunes "Buy Link" as part of the video description.
In YouTube's "Using copyrighted material in your video" it only says to get permission from the content owner (no specific details on how).
We are willing to pay for the original (e.g. buy it from iTunes), and add the buy link, but how do we do that? What's the specific process involved here?
