Billie Eilish's 'Bad Guy' was the song that ended the 19-week reign of 'Old Town Road' at number one. Produced by her brother Finneas in his bedroom, the track is famous for its minimalist production and Eilish's 'whisper-singing' style, which was heavily influenced by the ASMR (Autonomous Sensory Meridian Response) trend on the internet. The song's 'hook' is actually a synthesizer riff, and it features a surprising tempo change at the end. It won Grammy Awards for Record of the Year and Song of the Year. The track's success signaled a shift in pop music toward darker, 'weird' aesthetics and proved that professional studio quality could be achieved in a home-bedroom setting.
