Apple shares “6 out of 5 stars,” a song written from real App Store reviews

Apple closed out the WWDC25 keynote with a humorous surprise: a song titled “6 out of 5 stars,” written entirely from real App Store reviews.
The comical track, described by Apple as “dedicated to the people who develop the apps we love,” is performed by singer Allen Stone. He turns genuine user reviews into a catchy, nearly three-minute song, accompanied by piano and a live backing band.
