"Bad Habit" is Steve Lacy's breakout solo hit, built from regret, flirtation, and a deceptively relaxed groove. The song's lyric circles around missed romantic timing, but its sound keeps the mood light: dry guitar, loose bass, and a vocal that feels casual even when the feeling is specific. Its structure is unusual for a major pop hit, shifting through sections instead of relying only on one repeated chorus. That looseness helped it stand out online and on radio. "Bad Habit" also broadened Lacy's audience beyond his work with the Internet, showing how homemade funk and alternative R&B could become mainstream without losing personality.
