1. Robin Thicke - 'Blurred Lines'
Why we like it: Robin Thicke's effortlessly catchy hit has been sitting atop the Billboard Hot 100 for a whopping 12 weeks in a row now, and it's easy to see why: the song is a loose, funky blast of pure pop abandon.
Burn out factor: Decidedly low. The song's epic run at the top of the charts speaks to its sturdy replay value - months out from its debut, it still never fails to get people moving.
Will we remember it 10 years from now? Yes. Love it or hate it, "Blurred Lines" will go down as not only a massively-successful pop hit but a lightning rod for controversy, largely revolving around its racy video and lyrical content that's been dubbed "rapey" by a sizable number of bloggers and celebs.
