Why is a song by Scottish singer Annie Lennox, released in 1992 as the lead single from her debut solo album Diva, following her success with Eurythmics. Built around a searching, emotional vocal performance, it became one of her signature solo songs and has remained a familiar reference point for reflective pop. Decades later, short excerpts began circulating on TikTok, where creators repurposed its questioning tone for dramatic edits, nostalgic montages and personal story videos. Its lasting appeal lies in that instantly recognisable voice and the way a few seconds can suggest an entire emotional story.
