Alright so I was on YouTube then I found this amazing song, now it's not An actual song, mostly because it only lasts 5 seconds and it like switches to another song but I really really like the intro and want to know if it is an actual song and if so what's it called. Here is the YouTube link for the song, it's right in the beginning and only lasts like 5 Seconds.
