Songs from 2006, now a decade old

This article materialised in my Facebook feed yesterday evening:

http://www.thehitsradio.com/music/features/10-songs-that-are-ten-years-old-this-year/

I know almost all of those songs but the two that I find the most alarming on that list are Rihanna's "Unfaithful" and Justin Timberlake's "Sexyback". I remember those songs popularity as though it happened a few minutes ago. They're both ten years old now? Wow.
