Adele's song for Skyfall was leaked, at least a little bit, earlier this week.

But here it is in all its glory - LISTEN above and see what you think. Can it compare with some of the James Bond great themes - Goldfinger, Diamonds Are Forever, Nobody Does It Better, View To A Kill....?

Already, the song is rocking up the iTunes charts around the world after its release at 0.07am this morning.

The track has taken the top spot on the iTunes charts in Britain, Ireland, Greece, the Netherlands and Finland following its premiere on Adele's website in the early hours of Friday, which has been declared Global James Bond Day in honour of the franchise's 50th anniversary.

Skyfall also cracked the top five in the U.S. and Canada as fans rushed to download the song through the online music retailer.
