I'm going to put my money down and say the "Africa" was the 2018 song of the year thanks to the resurgence of Toto's 1982 hit by the alternative band, Weezer.
There is a brand new interest in the music and now people want to learn it and play it...on vegetables.
One YouTube user, Pupsi has hollowed out a few sweet potato's to recreate the hit song. And it's incredible.
Who knew you could do this!
