Apparently there are five scents that smell good to everybody. And they are:
1. lime (fruit)
2. grapefruit (fruit)
3. bergamot (similar to an orange in scent)
4. orange (fruit)
5. peppermint
And these are the runners up:
6. freesia (flower)
7. amyl acetate (a molecule that smells like apples and bananas)
8. cassia (similar to cinnamon)
9. mimosa (flowering tree)
10. fir (tree)
I've always found it strange that lots of perfumes include fruit notes. But now it makes perfect sense.
