"One Voice" is the title of a debut song written by David Malloy and Don Cook, and recorded by American country music singer Billy Gilman. It was released in May 2000 as the lead-off single and title track from Gilman's debut album One Voice. The song became Gilman's first (and only to date) Top 20 single on the BillboardHot Country Singles & Tracks (now Hot Country Songs) chart, making him the youngest singer to have a Top 40 hit on the country charts. Gilman was just 12 years old at the time.
"One Voice" debuted at number 71 on Billboard's Hot Country Singles & Tracks chart for the chart week of May 27, 2000. When the song became a Top 40 hit, Gilman became the youngest artist to chart a Top 40 country hit, edging out Brenda Lee to become the youngest person to ever have a song on the country singles chart. The song also became a Top 40 hit on the Billboard Hot 100 chart, reaching number 38.
Gilman's first music video shows him on the bus home from school and watches everything that goes on around him. At one point of the video a boy throws a gun into a river from bridge shown from a similar line in the song.
