Need some input on MUSIC!

[Road Apple]

So, I'm currently editing a gaming video and I'm basically finished. However, I need a song at the end of the video. So, lets say I wanted to use "Ad-supported music" like the song "Sorry" by Justin Bieber. What is yall thoughts on it? Good? Bad? Consequences for using it? etc....
