What is the best way to do categories you've seen?

If you have multiple groups e.g. football, tennis, cycling, make up, hair, etc - you can do it the old way of having a category header e.g. Sports and Women etc but it can be a pain for a user to find their specific group.

What is the best site out there which allows the user to find what they want quickly but without the pain?

I'm thinking spotify has a nice way of finding a track and finding the relative album etc via tags but i'm wondering about any others as well...
