During his speech at The BRIT Awards 2020, Lewis confirmed that contrary to popular belief, this song is about his grandmother (as opposed to an ex-lover).

The music video, starring the former Doctor Who star Peter Capaldi, depicts him as a widower. He is content, but when he meets a young mother and her family, who his wife had donated a heart to, and he gets to listen to her heartbeat again.

“Someone You Loved” was Lewis' first UK number 1 single and spent seven consecutive weeks at the top. It also hit #1 on Scotland and Ireland’s charts.
