EXO Comeback Preparation Record: Cheeks soaring at Sehun's praise and marveling at D.O.'s vocal tone

I watched the behind-the-scenes video of the recording for "Back It Up," a track from the 8th studio album, Crown.

It's cool to see the members putting so much effort into recording every single line.

Seeing the detailed direction going in from the beginning, asking to add breathing sounds to the parts

I immediately realized why the quality of this album is so high.

The process of choosing the better of the two versions and refining every single pronunciation was truly professional.
