"Let's Love" was a Japanese-only release from Melanie C's second album Reason. Released in Japan on 6 August 2003 and written by David Munday, Phil Thornalley and Melanie C, the single featured an instrumental of the track and two b-sides. The song was on a car advert for six months in Asia and also Australia for Toyota, and then a single was exclusively released in Japan. "Let's Love" had no music video. Pressings are very rare and sell high second hand.
