Hello everyone,
I made a 7 Seconds video to use it as an intro for my Udemy course videos.
I want to use a song called "legends never die(league of legends theme song)" on the intro video.
I can't find anything on google about the song license..
So I don't know if it's copyright-free or not.
Is it fine to use it on my intro? Its 7 sec into after all..
I'll include the intro video below, So u guys can watch it.
Thank you
