When posting on youtube for a year, leeching onto Reddit doesnt work, so asking RIOT is the way to g

So ever since SKT T1 won in 2015, me and lots of other people on youtube spent so many weeks into months and now years looking for the song that plays at 17:27 of the video link above. I've even emailed RIOT before and got no answer. People have made S5 worlds champion music playlist and claim every song from S5 is in the playlist but it does not include this song. This song is played also when Faker is asked to eat broccoli if he wins. Asking RIOT through email is ultimately useless as they respond in the most soul crushing way. So I'm asking the community to please help me.
