Secret - Madonna Like I feel tired for them honestly. The dance is constantly shaking their bodies non stop. This is by far one of the most tiring dances ever. Furthermore, there are only 4 members hence each member have to sing significantly more than other group's. Another hard song by them is "I'm In Love". Sistar - I Like That Sistar is known for their catchy dance moves, but "I Like That" is a different level. The dance is much more complicated than their previous dances. The dance is not as hard as other GG dances, but the song is A LOT HARDER to sing. Especially Hyolyn's and Soyou's verses, Hyolyn with her powerful voice and Soyou with her constant transition between chest to falsetto voice. T-ara - Lovey Dovey Is shuffling tiring? Imagine shuffiling AND SINGING. They are literally SHUFFLING THE ENTIRE 3 MIN. It might not look that hard, but just try it for 3min. Gfriend - Rough Don't think this song needs any introduction. In fact, almost all Gfriend songs are extremely hard, let alone sing and dance to them. Wonder Girls - Like This Similar to Lovey Dovey, they are constantly jumping around non stop. SNSD - Into The New World Their debut song + one of their hardest songs. "Catch Me If You Can" is another, but I still think their debut song + dance is really impressive Red Velvet - Dumb Dumb Whoever that thinks this song is easy to sing + dance at the same time has to be dumb dumb dumb dumb, dumb dumb dumb dumb dumb dumb. Of course there are many others. What are some GG song + dances which are hard to perform live?
