What is the highest-charting Coldplay single on the US Billboard Hot 100?

Coldplay's highest-charting single on the US Billboard Hot 100 is "Viva la Vida." Released in 2008, the song reached number one, becoming Coldplay's first US chart-topper.

The track was the second single from the album Viva la Vida or Death and All His Friends, following "Violet Hill." Its orchestral arrangement, prominent strings and dramatic lyrics about a fallen monarch gave Coldplay a different sound from the piano-led intimacy of earlier hits such as "Yellow" and "The Scientist." The song's title comes from a painting by Mexican artist Frida Kahlo.

Several other Coldplay songs became major American hits, which can cause confusion. "Speed of Sound" was previously the band's biggest Billboard Hot 100 success, peaking at number eight, while "Clocks," "Yellow" and "Fix You" are among the group's best-known songs but did not reach number one on that chart. "Viva la Vida" also topped the UK Singles Chart and won the 2009 Grammy Award for Song of the Year.
