The fourth song of BoA's 20th-anniversary project "Our Beloved BoA" will be released on August 21.

"Milky Way," sung by Red Velvet, will be released on various music sites at 6 p.m. on August 21, and live videos will also be available simultaneously through YouTube's SM's "STATION" channel.

"Milky Way" is a track from the third full-length BoA album released in 2003, and KENZIE, who made the original song, reinterpreted it as a jazz-pop genre once again, and with colorful a cappella and jazz scats featuring the harmonious vocals of five members of Red Velvet, it is enough to give a refreshing and summer-like feeling.
