"Sober Up" is a song by American indie pop band AJR, from their second studio album, The Click.

The inspiration for "Sober Up" came to Jack and Ryan Met during their time at Columbia University, the brothers missing their childhood.

Taking inspiration from their feelings of loneliness, they wrote about Jack calling his second grade crush from elementary school.

In the music video, the band is walking through New York City while singer Jack Met meets a younger version of himself that is only visible in reflections.

For Rivers Cuomo, "Sober Up" was his first song to reach number one on Billboard's Alternative chart as a solo artist outside of Weezer.
