The single also entered the UK top 75 at #59 on downloads alone, a week before the song's physical release on 20 November 2006. "Someone Should Tell You" climbed to #21 on its release and became Lemar's second single to miss the UK top 20, joint lowest with "Don't Give It Up" which also made #21 in 2005.
