I need the song from the background of the tech test trailer
It’s probably copyrighted, even though I would ask proper person if I can use this track, even if it is for non profit purposes.
Shazam from Apple? Or any other app that can identify music!? 
Or try to upload the video to your account in YouTube. It will tell you what is the name of the music and who is the creator! 
You can get a video from YouTube of the menu music and get a YouTube Video convertor and paste the link in the converter and it will make the sound file for you, the app i use is clip grab and works pretty well.
A teaser trailer wouldn’t have the whole song.
Are you talking about “And the crowd goes wild”?
I think that’s the song, but I can’t find that version.
