While Wonder Girls always touted a throwback-inspired image and sound, the group typically focused on '60s- and '70s joints. With Reboot, the girl group not only proved to still have their knack for super-smooth and catchy tunes, but also proved the strength and versatility of their concept. Album standouts like "Candle," "Baby Don't Play," "One Black Night," "Loved" and the LP's lead single "I Feel You." utilize the mainstream, Madonna-like synth-pop sound of the '80s. At the same time tracks like "Back" play off the early rap beats (think Run-D.M.C.) that were beginning to garner attention at the time, while album closer "Remember" sounds like an old-school ballad with synthy piano one could imagine George Michael busting out.
