Which license for multi-use needs

Hi, I have questions about licensing in several scenarios. Which one is ok for:

-A theme for a youtube video series / podcast. Or in my case video game developer diary. Lets say there is an opening piece that gets used over and over in new episodes but essentially the product where the audio was used is the opening sequence itself.

-Video game and it’s related streaming. I want a song for an indie game. Fairly simple. How about all videos where I capture myself (or another player captures themselves) playing said game. Are these covered by the original license for the game? and which license should be used.

thanks a lot.


Answering myself.
The youtube etc.“opening” question was answered here:
