"All About That Bass" is the debut single by American singer-songwriter Meghan Trainor, released on June 30, 2014, through Epic Records. The song was included on Trainor's debut extended play (EP), Title (2014), and her debut studio album of the same name (2015). The track, a bubblegum pop, doo-wop and hip hop record, was recorded from 2012 to 2013 at the Carriage House, based in Nolensville, Tennessee, and Sun Mountain Studios, based in Boiceville, New York. It was written by Trainor herself, alongside Kevin Kadish, who also produced the song. Trainor, who as a teenager struggled with her negative body image, was inspired to write the song to promote self-acceptance and body positivity.
