It's hardly a common song in any way at all, unless you happen to know it's also a meme.
As a song, it's joyful and happy-sounding, just due to the fact that it's sung like it's a laugh. (Not the original intention of the song, but that doesn't change the fact with this version).
The song fits the advert. I don't think it's being used to gain the interests of those who spend their time on the internet learning about memes.
