It Must Be Love (Labi Siffre song)

It Must Be Love is a song written and performed by British singer-songwriter Labi Siffre, released in 1971 on his album Crying Laughing Loving Lying. The song is a gentle, romantic ballad characterized by its simple melody, Siffre's heartfelt vocal delivery, and a prominent string arrangement. While not initially a major chart success upon its release, "It Must Be Love" has endured as a popular and critically acclaimed song, largely due to its subsequent covers and enduring appeal.

The lyrics express the sentiments of a person deeply in love, describing the overwhelming emotions and joy associated with the feeling. They avoid complex metaphors, instead focusing on the raw and honest expression of affection.

The song gained significantly more recognition in the 1980s when it was covered by the British ska/pop band Madness. Their upbeat and energetic rendition, released in 1981, became a major hit internationally, reaching the top 5 in the UK and achieving success in other European countries. Madness's version is notable for its distinctive ska-influenced arrangement and the band's signature playful energy, which contrasts with the original's more subdued tone.

Due to the commercial success of Madness's cover, many audiences are more familiar with their interpretation of "It Must Be Love" than with Siffre's original recording. Nevertheless, both versions are well-regarded and contribute to the song's lasting legacy. The song continues to be featured in films, television programs, and advertising, further solidifying its status as a classic love song.
