Bonus: Lightweight

Foobar2000 has a relatively small memory footprint, compared to similar featured media players.
I don't know if there are benchmarks, and it also depends largely of your foobar2000 configuration, but in my personal case, it loads much faster than winamp.

Also, the library search is instant (with an old hardware config and about 9.000 tracks), whereas it's getting a bit slow with winamp these days.

I don't know if use graphic skins changes that.
