According to the TOS linked above.

• I cannot put FF14 music in the intro OR outro of my videos - because the original footage doesn't accompany it.
• I cannot put my own third party music on top of the footage I record.
• I cannot chop up the game sound / music - and because I cannot edit the video without chopping the audio, I can't upload it.

^ Stupid.

You made the decision to allow monetization on YouTube (shouldn't have even been an option) and you need to make the decision to remove this stuff from your TOS. It's silly.
