Backstreet Boys — Shape of My Heart

A Max Martin ballad from the back end of the boy-band era is broadly charting today, tracked across 50 country and platform charts — nearly double its recent run rate. The likeliest engine is the group's ongoing 2026 tour revival, billed by Backstreet Tour as the biggest of their career, alongside a Las Vegas Sphere residency that has spread across TikTok. Released as the lead single from Black & Blue in 2000, the track was, per Billboard, the first "man-band" hit — the moment a group built on bubblegum choruses reframed itself around growing past old mistakes, with five members staring down their thirties. Co-written by Lisa Miskovsky with Martin and Rami Yacoub, it traded teen-pop gloss for soft-pop guitar and a more sober lyric. The catalog has rarely been this active across so many markets at once.
