Oh Joon-sung, who was the music director for Boys Over Flowers, was criticized for overusing songs at the time of drama's airing. The soundtrack was popular and fared well on the music charts. "Paradise" by T-max, of which Kim Joon was apart of, served as the drama's opening theme. Kim Hyun-joong's band SS501 performed "Because I'm Stupid" (내 머리가 나빠서), the ending theme. Several insert songs, such as Someday's "Do You Know" and Shinee's "Stand by Me", were included on the soundtrack.
