Timeless Classic:
1. Baby one more time
2. Toxic
3. Oops I did it again
4. Slave
5. Everytime

Not classic but iconic/memorable:
1. Till the world ends
2. Gimme More
3. Piece of Me
4. Womanizer
5. Circus

Just a hit:
1. 3
2. Hold it against me
3. I wanna go

Good single even if flop:
1. Sometimes
2. Lucky
3. Born to make you happy
4. Not a girl not yet a woman

Underrated:
1. Stronger
2. Overprotected
3. If you seek Amy
4. My prerogative
5. Do something
6. Work bitch
7. You drive me crazy
8. Break the eyes

Lucky to be a single:
1. Criminal
2. Perfume
3. Radar
4. Me against the music
5. Outrageous

Oops is actually more remembered than Toxic and Baby. Mods, please close this mess.

Why close it? It's my opinion and you can do yours.

BOMT is definitely her most memorable. I feel like OIDIA is more iconic but toxic is more current.
