The song's lyrics depict a one-sided obsessive relationship from the point of view of the pursuer, who implores the object of his affection that she needs to "spend some time" with him so that he might "possess [her] heart." The song is written in the key of
D, but the main motif continually switches modes from major to minor as the chord goes from D to F with a moderate tempo of 134
beats per minute. The music is dominated by a distinctive 4-
bar bass guitar
riff that is repeated through nearly all of the song. This is interspersed with piano chords that generally follow a D–D/C–F–G
progression. The lead vocals have a range of D3–G4. The instrumentation also includes multiple guitar parts, drums, and backup vocals. Gibbard characterized the song as "five minutes of build and then a three-minute song", Harmer said of the bass line, "I immediately gravitated to the creepy, stalker-ish theme that Ben created with the lyrics and the piano chords.... I liked the idea that once a stalker gets obsessed with an idea, it just keeps repeating in his head, so I wanted the bass line to have a repetitive, incessant theme." The song was released on March 18, 2008, initially as a "surprise stream" on the band's website, and soon after was picked up by radio stations. It was released in two versions: the album version of the song is over eight minutes long, while the radio edit largely removes the instrumental introduction, shortening the song to four minutes. == Reception ==
