Album: One in a Million (1996)

Ballads were not a significant part of Aaliyah's exemplary catalog, but records like "The One I Gave My Heart To" proved baby girl could switch from her usual mid-tempo style and deliver an incredible vocal performance. A single from her seminal release One in a Million, "The One I Gave My Heart To" was penned by Grammy Award-winning songwriter Diane Warren and produced by Daryl Simmons, although the slightly pop-edited single version was produced by Guy Roche. Aaliyah brought the song to life through her smooth soprano vocals, highlighting a broken heart and sense of betrayal, with the accompanying video perfectly depicting her emotional state. "The One I Gave My Heart To" climbed to No. 9 on the Billboard Hot 100, becoming one of Aaliyah's most commercially successful singles. —Edwin Ortiz
