It turns out that EXO’s December, 2014 isn’t exactly an original composition.
SM Entertainment heard the original song, “Long Time, No See” sung by K. Michelle.
They liked it so much, they purchased the rights to the song and re-arranged it a bit for EXO’s vocal line.
Check out K. Michelle’s version of the song in the video below.
Both versions sound wonderful.
It is a bit disappointing that SM didn’t hire composers to create an entirely original song for EXO though.
But nonetheless, the song sounds great and it’s a wonderful gift from EXO to EXO-L.
