On November 25th, Billboard has released it's 100 Greatest K-pop Songs of the 2010s to commemorate the decade in K-pop.

Amongst the top 100, the top spot goes to IU's Good Day (Real,2010) stating that it is the "epitome of K-pop's rare ability to cross unexpected genres and make them mainstream, as orchestral instruments harmonize with unexpected blasts of brassy horns". It is also mentioned that this song can only be pulled off be IU, unleashing her full potential with each high-pitched climactic note hits on each refrain.

Red Velvet has also shined with 2 songs, Red Flavour (The Red Summer, 2017) and Bad Boy (The Perfect Red Velvet, 2018) on the list for 2017 and 2018 respectively. Red Flavor has been an undeniable hit and has been ever-beloved by fans worldwide. Red Velvet has proven how versatile their music can be through the release of Bad Boy, showcasing "how tactile the sonic and visual layering of the song is -- touching on the softness of each member before swelling into a sweeping chorus of harmonies". -L.S.
