Sam Smith's much anticipated theme to forthcoming Bond film 'Spectre' is out today.

The song, a sweeping orchestral ballad called 'Writing's on the Wall', sees the 24-year-old following in the footsteps of artists as diverse as Nancy Sinatra, Lulu, Adele, Tina Turner and Shirley Bassey.

The song was co-written by Smith - who reportedly wrote the lyrics in half an hour - and his regular collaborator Jimmy Napes, and was recorded as far back as January.

What do you reckon? Potential future Oscar winner?
