"Lost in You" is a song co-written by Gordon Kennedy, Wayne Kirkpatrick, and Tommy Sims. It was recorded by American country music artist Garth Brooks under the fictitious persona of Australian alternative rock artist Chris Gaines. It was released in July 1999 as the lead single from the album Greatest Hits. Originally, the album was intended to be the soundtrack for a movie called The Lamb that would star Brooks as a rock star recalling the different periods of his life. The single was purposefully released over a year in advance from the scheduled film release date to pique interest in Brooks performing rock instead of country. The Lamb, however, was never filmed due to financial and management problems. It peaked at No. 5 on the U.S. BillboardHot 100 chart.
Deborah Evans Price, of Billboard magazine reviewed the song favorably saying that it is a "gentle, beautifully produced love song." She goes on to say that it contains easy beats, "supple guitar strumming" and a chorus that "flows like a lazy steam on the most pleasant of days."
