Hello, Ove Melaa!

I need to use your song in my game teaser trailer video. I want to publish trailer on Steam page of my game and to my YouTube channel.

So I have a question about credits:

Do I have to mention "XXXXX (score name) written and produced by Ove Melaa (Omsofware@hotmail.com)" in the description of my game on Steam and under Video Credits section of teaser trailer in YouTube channel?

Or do I have to mention "XXXXX (score name) written and produced by Ove Melaa (Omsofware@hotmail.com)" directly in the video itself?

Or (the best way) can I mention "XXXXX (score name) written and produced by Ove Melaa (Omsofware@hotmail.com)" in game credits when the game will be released?
