If you’ve not already heard “Titanium” on the radio, Sia‘s massive dance floor anthem crafted alongside David Guetta (and one of my Top 10 Singles of 2011!), fear not–you’re about to.

Having already peaked at #1 across the pond in the UK in early February (as well as hitting Top 10 in dozens of other countries), the track now stands at #63 on the Billboard Hot 100, already a giant leap up from last week’s #79.

To celebrate, MuuMuse is giving away 5 “Titanium” prize packs.

Each prize pack contains ONE remix CD featuring mixes by Alesso, Nicky Romero and more, plus ONE “Titanium” T-shirt which looks like…THIS! To enter to win, simply leave a comment below with the following phrase:


Five winners will be contacted via email on Monday, May 14. US entries only, please!

“Titanium” was released to US radio on April 24. (iTunes)
