This was The Killers' first ever recorded song for their 2002 demo. The song was composed by guitarist Dave Keuning and the lyrics written by Brandon Flowers. It was re-recorded and released as a single in 2004.

Despite its upbeat feel, the song deals with issues of infidelity, paranoia, and jealousy. This is due to Brandon Flowers' heartache when his ex-girlfriend cheated on him while they were together.

The single went 2x Platinum in the US, selling over 2 million copies and is 3x Platinum in the UK, selling almost 1 million copies. It has also clocked over 200 weeks in the UK Top 100, more than any other song.

The single also won ‘Best New Artist in a Video’, ‘Best International video’ and is often referred to as one of the best songs of the 2000’s.
