In August 2004, Selwyn released "Boomin'". It was written by Paul Rein for Selwyn's second studio album, One Way. Australian singer Israel contributed to the production of the song, which according to Kathy McCabe of The Daily Telegraph is "beefed-up". Selwyn described it as a "different track" with a "different feel". It was promoted through the clothing store Jay Jays, where customers would receive a physical copy of the single after spending $40 at the store. For the week of 19 August 2004, "Boomin'" was the third-most added track to the playlists of Australian radio stations. It entered the Australian Singles Chart at No.28 and spent six weeks within the chart.
