The album is famous for having one side of up-beat songs and a second side of melancholic ballads. On the first half, "When I Grow Up (To Be a Man)," "Dance, Dance, Dance" and "Do You Wanna Dance?" were all hits, and "Help Me, Ronda" would be worked on further to deliver the Beach Boys their second #1 hit in May.(amid a small spelling change in the title). The second side, in retrospect, was an indicator to where Brian Wilson was going musically. Considered darker and more meaningful than previous softer works, alongside Wilson's increasing productivity in the studio, the ballads on the second side are thought of as a precursor to Pet Sounds' technical triumphs, including strings, horns, piano and keyboards, more percussion, and volume tricks.
