Basically every 2nd gen k-pop album in a nutshell.
This album had very fun moments like the singles, and i enjoyed most of the b-sides.
Oh! was pop perfection, boys and girls was easily the best and funnest b-side, and genie is just one of the best moments in the k-pop industry.
The big problem w the album is that it's messy. SM decided to randomly dabble in some ballads in the tracklist.
