"Aaliyah" frankly left too early - it's one of Jessie's greatest vocal performances. I feel like the duality in the song is really striking - it's Aaliyah hagiography, immortalising her as this unimpeachable goddess, but I think the "Aaliyah" figure is also presented like just some girl at the bar like "my friend Olivia" from Katy's "Easy Please Me". Either way she has both Jessie and Katy "transfixed", but at the same time she's cruel, and provoking jealousy. The whole thing is an exercise in suspense - "Aaliyah" came out at a time when wordless choruses were becoming the norm in British chartpop, and I sort of like the fact that the drop never arrives, and you're just suspended in endless, UK-funky space. A banger!
