"Tongue Tied" received mixed to negative reviews from critics, with criticism directed towards the use of synthesizers. Despite its reception, it remains one of the band's highest charting singles to date, becoming their first song to chart on the Billboard Hot 100, where it peaked at 42, as well as number 3 on the Rock Songs chart. The song has been performed on various late-night talk shows, as well as on the American musical comedy-drama television series Glee.

"Tongue Tied" was written by the collective members of Grouplove and produced by Ryan Rabin. The song was recorded by Rabin at Captain Cuts Studios in Los Angeles, California. According to lead vocalist Christian Zucconi, "Tongue Tied" was conceived in swift fashion. While composing the piano score for a "really depressing, moody movie", Zucconi began to play around with various chords before settling on a melody. He then performed an instrumental version for bandmates Hannah Hooper and Sean Gadd.
