2. Nobody Else - A sensual cut keeps the flirtatious vibes, but ups the sensuality with surging synths and slick harmonies. There's sexy little hook in here, but it's far from bubblegum, giving the song another understated and sophisticated feel. With lyrics written by and production helmed by member Junho, "Nobody Else" confirms the record's understated, alluring feel.

3. Hallucination - Another sexy, R&B-pop knockout that matches with the earlier two tracks. "Hallucinations" is the work of K-pop producers e.one, who are on a roll this year -- also producing Kara's "Cupid," which had a similarly subtly sophisticated feel to it.
6. About to Go Insane - The bouncy electro-pop production gets mixed with unexpected brass and grungy guitars for one of the record's most intriguing instrumentals so far, giving the LP a refreshing sonic shift at the right moment.

7. Red - The kind of slow jam that 2PM has a specialty for, "Red" is a standout that's sure to make fans melt. The guys' vocals easily glide over the slinky track with a cool sonic moment as their boy-band belts back another sexy rap from Taceyceon on the bridge.
10. Magic - The tempo gets picked up with this swing-y, throwback track with the blasting brass. Listen up for fun lyrics about having tricks up their sleeves, asking their love interest, "Is this your card?" for a playful feel here.

11. Jump - The most EDM-inspired track on the album, "Jump" keeps the "Magic" energy high and surges through a zippy production of trap snares and spastic synths. Even though the production clearly belongs in 2015, the simple chorus is reminiscent of early boy band material like New Kids on the Block. Along with "About to Go Insane" and "Magic," this is the third No.5 cut written and produced by Taecyeon and new 2PM collaborator Raphael. The duo clearly have a knack for exciting, atypical pop-R&B productions.
12. Good Man - Like most K-pop albums, No.5 ends with a ballad, but there's a definite seductive nature still here, but the classy jazz production (co-produced by Chansung) is a grown and polished type of flirt. The guys' vocals slide through the chorus, promising to be a "good man" before an awesome saxophone solo leads them to next sections. There's no humongous climax moment here, but instead it's a sophisticated album closer that truly shows that 2PM has officially grown into gentleman, even with a more mature outlook, they're sounding just a hot as ever.
