We thought this long before we decided to have a competition about it, but Toxic by Mark Ronson is already a contender for single of the year and deserves to be number one forever – and if you haven't heard it, now's your chance to win a free copy.

Toxic is the first fruit of genius British ex-pat DJ Mark Ronson's forthcoming Versions album – an album that we would happily put a pensioner in intensive care to get hold of – and, yes, it's a cover of the Britney Spears song. But what a cover – Mark Ronson reimagines Toxic as a horn-drenched soul anthem featuring a guest-rap from dear dead Old Dirty Bastard. Mark Ronson's version of Toxic is punchier than Britney's, more joyous than Britney's and one thousand percent less likely to show you its vagina. That's a good thing, by the way.

But, look, we'd happily bleat on about the innate brilliance of Toxic by Mark Ronson until the end of time, but we don't need to. We've got two 10" white label copies of Toxic and two CD copies of Toxic to give away to you instead. Fancy winning them? Answer this question, then:

What's the best way to make sure that Britney Spears never shows us her bare vagina again? 

The four funniest answers all win a copy of Toxic. Email your answers to hecklerspray[AT]gmail.com with the subject 'Britney's Toxic Vagina' along with your format preference (white label or CD). If you win, we'll be in touch shortly.

Good luck people.
