Regarding this, can I use popular music in my YouTube video?
Yes, you absolutely can use copyrighted music on YouTube, as long as you get the permission from the copyright holder. Get your music from a reputable music provider.
Likewise, can I use a cover song in my video? Cover song videos are NOT protected by a mechanical license.Once a song is published, you have the right to cover it (as a recording, but NOT as a video).
Besides, can I use 30 seconds of copyrighted music?
You may have heard of "fair use," a copyright provision that permits you to use 10, 15 or 30 seconds of music without copyright obligation. That is, you understand that you can use a short section of a song without paying a fee. Yet, you're wondering how exactly this works. The short answer is that it doesn't work.
