Butterfly (1997) if Sony commercially released the following singles in this order:
- Honey
- Babydoll
- The Roof
- My All
- Fourth of July
But Sony didn't commercial release some singles because they didn't like the direction Mariah was heading towards to.
For
Britney (2001), Zomba should've been more wise.
- I'm A Slave 4 U
- Don't Let Me Be The Last To Know
- Anticipating
- I'm Not A Girl, Not Yet a Woman
- I Love Rock N Roll
If Zomba and BMG released I'm A Slave 4 U as either a Cassette or CD single other than a irrelevant 7'' single, then it would've went number one and it would've been more convenient.
