Thanks to TikTok, We Can't Get These Songs Out of Our Heads

Twenty-twenty marked the year that TikTok took over our lives, and this year has been no different. People everywhere have been flocking to the app searching for hacks to simplify their lives, delicious recipes to cook at home, dance routines to re-create with their friends, and makeup tutorials to try out. Along the way, TikTokers are also being introduced to music they've never heard before and sometimes they're even reintroduced to songs they forgot about. Case in point: remember Busta Rhymes's 2006 hit "Touch It"? Or, how about 1978's "Rasputin" by Boney M.? Well, both classics are making the rounds again, thanks to TikTok. Ahead, check out the most popular songs on TikTok in 2021 so far.
