From contributing songs to Christina Aguilera's era-defining "Bionic" album to single-handedly saving dance music with "Titanium", Sia has done it all. Or at least I thought she had until I spotted her as the feature vocalist on Hilltop Hoods' latest single. Yes, my fellow Bey stan can now add edgy hip-hop diva to her CV. This is getting ridiculous! I'm not going to pretend I'm huge Hilltop Hoods fan from way back but the Aussie MCs have churned out some amazing singles over the past decade so - "The Nosebleed Section" and "Chase That Feeling" spring to mind. You can now add "I Love It" to that list. The track finds the boys in top form, trading lyrical blows as Sia chirps her way through the kind of chorus that gets lodged in your brain and refuses to leave. Like that demon slug in Supernatural. Adelaide's two biggest musical exports have served up a sure-fire smash, with the track already sitting at number 12 on iTunes with no video or promotion. Expect to be hearing this all summer long!
