"Juliette" by SHINee is a remake of "Deal With It" by Corbin Bleu. You'll notice the 90's vibes in both songs, but more electronic funk-infused in "Juliette". You might also recognize Corbin as Chad from 'High School Musical'. And by the way, Taemin is 16 in that video!

"Whatta Man" is a remake of the song by the same name by Salt 'N Pepa. I.O.I's take on the song was met with a faster tempo and some more powerful instrumentals. And of course, Yoojung and Nayoung's fire rap lines.

"Happiness" by Super Junior is a remake of the song by the same name by H.O.T. Super Junior's strong vocals and choreography really did justice for the hit '90s group!

"Girls' Generation" by Girls' Generation is a remake of the song by the same name by Lee Seung Chul. Though Girls' Generation were the ones to bring the song to international stardom, Lee Seung Chul was the original architect of the catchy song.

"Round and Round" by T-ara is a remake of "Round Round" by an 80's Korean artist named Nami. You can hear the near-identical choruses in both songs. T-ara changes it up with a more modern soundtrack and a cuter concept.

"This Love" by Big Bang is a remake of the song by the same name by the wildly popular group 'Maroon V'. However, the entire song is performed by G-Dragon.

"Hot Summer" by f(x) is a remake of the song by the same name by 'Monrose'. Though f(x)'s version features a fun and girly concept, the original version embodies a more sexy concept. Check both out!

"Come Back Home" by BTS is a remake of the song of the same name by the legendary group 'Seo Taiji and Boys'. Much of the original lyrics and beats are preserved in the remake, but you can hear BTS' trademark hip-hop swagger infused into the song. And hey, is that YG in snow gear???

"My Old Story" by IU is a remake of the song of the same name by Cho Deok Bae. Her beautiful vocals conserve the soft and soothing feeling from the original but add a dimension of her own!
