"3AM" is the third single to be released from Swedish producer and singer-songwriter Kleerup's debut album. "3AM" originally appeared, in a different form, as a B-side to fellow Swede Marit Bergman's single "Mama, I Remember You Now"; she wrote the lyrics and vocal melody for the song, while Kleerup provided an original instrumental for the version that appears on his album.

In May 2008, when the album was released, "3AM" charted due to extensive downloading. It charted at #52 on the Swedish singles chart, and enjoyed a two-week run.

Upon the singles official release, it re-charted and reached a new peak position of #35.
