This album is SINFULLY good. Honestly, one of the sexiest albums in Kpop that I have ever heard. Sin and lust are the two words to describe this album. As good as the title track "Red Moon" is, the other songs are just as good or better. "SINphony" and "Beautiful" are probably my favorites. I immediately checked out the album after watching the Red Moon MV. I didn't even get halfway through the Intro song and I was like, "... yep I'm buying this."
