Not Now

"Not Now" is a song by American rock band Blink-182. It was released in November 2005 as the sole single from the group's first compilation album, Greatest Hits (2005), through Geffen Records. "Not Now" explores concepts of death and its impact on those one leaves behind, and was written from the perspective of an out-of-body experience. Stylistically, it builds heavily around the band's trademark power chords and guitar riffs, and also employs a church organ to achieve a funereal atmosphere.

"Not Now" shares writing credits between the band's three members: guitarist Tom DeLonge, bassist Mark Hoppus, and drummer Travis Barker. It was produced and mixed by Jerry Finn. "Not Now" would be the band's last single before their four-year hiatus from 2005 to 2009. As the band had broken up by its release, the song's music video recycles clips from their past videos, concerts, and tours.

An outtake from the band's untitled 2003 album, "Not Now" had previously been released as a standalone single for iTunes and elsewhere prior to its inclusion on Greatest Hits. The song reached number 18 on Billboard's Hot Modern Rock Tracks chart and number 30 on the UK Singles Chart.
