I decided to double the points given for each topic permanently. I don't have the time to update constantly so it would take too much time to get to 500 points with the old system.
RESULTS: What's your favourite Britney Spears' lead single?
1. Gimme More - 40%
2. I'm a Slave 4 U - 26.67%
3. ...Baby One More Time - 20%
4. Hold It Against Me - 6.67%
4. Work Bitch - 6.67%
Oop, I chose the 3rd option this time But now I'm up to #4 on the main chart, yassss
My top 9 (for now):
1. ...Baby One More Time
2. Me Against the Music
3. Oops!... I Did It Again
4. Womanizer
5. I'm a Slave 4 U
6. Gimme More
7. Work Bitch
8. Hold It Against Me
9. Pretty Girls
Britney's lead singles are all great but I must admit that none of these are even in my top 10 songs from her. I feel like she has better single choices later on in her eras.
But now I'm up to #4 on the main chart, yassss 
This is my first time playing.
