About NO

"No" (stylized in all caps) is a song recorded by American singer-songwriter Meghan Trainor for her second major-label studio album Thank You (2016). Ricky Reed produced the song and wrote it with Trainor and Jacob Kasher Hindlin. Epic Records released the track on March 4, 2016, as the lead single from the album. Featuring guitars in its instrumentation, the dance-pop and R&B song draws influences from doo-wop, with lyrics about unwanted advances from men towards women. Music critics compared the song's composition to pop artists of the late 1990s and early 2000s, including Britney Spears and NSYNC. "No" peaked at number three on the US Billboard Hot 100, and also reached the top 10 in Australia, Austria, Canada, Israel, Latvia, South Africa, and Scotland.

Fatima Robinson directed the music video for "No". It features Trainor performing alongside an all-female dance troupe in a warehouse. Critical commentary compared it to the works of Spears and Madonna for its sexual nature, and identified it as new territory for Trainor due to its darker palette. Trainor performed "No" on television shows such as the 3rd iHeartRadio Music Awards, The Graham Norton Show, The Ellen DeGeneres Show, and the 2016 Billboard Music Awards, and included it on the set list of her The Untouchable Tour (2016).
