Toto has recently been enjoying renewed interest, probably part of a general 1980s nostalgia trend. Weezer releasing “Rosanna” after fans kept pestering them to remake “Africa” (a genius counter-troll), before then releasing “Africa” itself, brought Toto to the national fanfore in a way nostalgia alone never could.
And, to be honest, I think “Rosanna” is the better song. If you don’t believe me, listen to this guy. I love “Africa” (and, MF, I can sing it!) but Rosanna is musically superior, even though “Africa” is a tough competitor and has a better backstory.
