I'm a huge fan of covers. Lots of my favourite artists will take a great song (or even a bad song) and do something really interesting and different and clever with it, like Jonathan Coulton's cover of "Bills, Bills, Bills", or Johnny Cash's cover of "Hurt", or Carolina Chocolate Drops cover of, well, nearly everything they've ever covered.
I'm also a huge fan of Tears for Fears, so the idea that someone was doing covers of music I already like was pretty exciting.
And then I actually heard Lorde's version of the song. And I was fucking blown away. It's such a good version of a great song, with a totally different vibe just by changing key and pace. It's a brilliant cover and I can't help but like it basically every time I hear it.
