Yes, it would do much better
If the album wasn't attached to a movie, wasn't named "Glitter", "Loverboy" had the original "Firecracker" sample Mariah intended to use and "All My Life" was released as a second single.
The album was artistically great. It just wasn't given a chance and was sabotaged by Tommy.
But yeah, '80s inspired music has seen a resurgence and "Glitter" was a brilliant revisitation and interpretation of that era. Her vocals were excellent, some of the best she's ever put on record.
