“Automatic” is a song recorded by South Korean girl group Red Velvet for their debut extended play Ice Cream Cake (2015). Written by lyricist Choi So-young of Jam Factory and produced by Daniel “Obi” Klein & Charli Taft, the contemporary R&B track was released as the group’s first single (marketed as a pre-release single previously) from the EP on March 14, 2015 by S.M. Entertainment, along with an accompanying music video. It marks their first release as a quintet since the addition of their fifth member Yeri, and also the group’s second single to follow their “Velvet” concept, following the digital release of their second single “Be Natural” in 2014.
Upon its release, the song has been regarded as one of the group’s signature “Velvet” songs and received positive reviews from music critics due to its sultry and minimal production. Commercially, the song charted moderately on the Gaon Digital Chart and US Billboard World Digital Song, peaking at number 32 and number 9 respectively.
