The video shows a split screen of Amiel and a man who both enter a restaurant and sit down. Part way through, they both go to the bathroom and end up coming out on the opposite side of the screen and finish sitting at each other's seat and being brought the other's meal.
Amiel wrote the song in 1999 when she first moved to Sydney, New South Wales. She states "I went out with this guy, it was three dates, just dinners, it was so irrelevant, it was completely nothing. I was new in town and I wanted something, someone. But it was a waste of time. I thought: great, all I got out of that was a love song, another fucking love song." Amiel states that the lyrics were changed to "stupid Lovesong" for radio because "stupid" preserves the sentiment better than a beep.
"Lovesong" was commercially successful in Australia. On its first week of release to radio it became the most added song to Australian radio for that week. In March 2003, it debuted at number thirteen on the Australian ARIA Singles Chart and within five weeks of its release, it had reached the top ten; becoming Amiel's first top ten single. It went to peak at number six and stayed at that position for one week. The single spent twenty-six weeks on the Australian ARIA Singles Chart, seventeen of which were in the top fifty. The song went to become the thirty-fourth highest selling single in Australia for 2003 and the Australian Recording Industry Association awarded the single a platinum certification for shipping 70,000 copies. The song was nominated for two ARIA Awards as the "Highest Selling Single" and "Single of the Year" for 2003, but lost both awards to "Born to Try" by Delta Goodrem.
