I hardly ever buy music and I just bought this song off iTunes, love it! You're right it's so catchy!!
Love love Gotye, be sure to check out the rest of their stuff. And while you're at it check out more of Kimbra as well, especially "Settle Down." You have great taste.
Holy Moly I am getting myself to Target ASAP! Hopefully mine still has some of the lovelies you scored. Nice finds!
