"Let Me Go" was released as the third single from Lavigne's self-titled fifth studio album on 15 October 2013, after the release of the first two singles, "Here's to Never Growing Up" and "Rock N Roll". Lavigne described it as a piano ballad and one of her favorite songs from Avril Lavigne. "Let Me Go" features vocals from Lavigne's husband, Nickelback frontman Chad Kroeger, whom she married in July 2013. The song was first written in March 2013 and was originally going to be about letting go of someone, but after Lavigne's and Kroeger's relationship started growing, they rewrote the last chorus to reflect it.
The song premiered on 8 October 2013, 8:30 AM (PST) at KBIG 1043 MYfm and has been released on the iTunes Store a week later on 15 October 2013.(wiki)
