A Class is the debut studio album by South Korean-Chinese girl group Miss A.

The "Breathe" music video shows the Miss A members dancing in a room with stripes of various colors.

JYP CEO Park Jin-young uploaded a video of himself at a recording studio with Grammy-winning mixing engineer Manny Marroquin, who has worked with artists like Whitney Houston, Alicia Keys, Kanye West, and Bruno Mars.

He also showed a 15-second preview of the group's new song "Goodbye Baby", which eventually became the album's lead single.

The album's next single, "Love Alone", was specially created for South Korean figure skating champion Kim Yuna's "Ice Show".
