James Bond fans have welcomed Adele's "classic" theme for the latest 007 film after a short clip was released online.
She has teamed up with Paul Epworth, who co-wrote and produced her massive hit Rolling In The Deep, to write Skyfall for the new film of the same name.
Adele has previously said she was "hesitant" about recording the song.
The track, recorded at Abbey Road Studios in London with a 77-piece orchestra, will get its first full play on the singer's website at 0.07am on Friday.
The film, again starring Daniel Craig as Bond, is to be given its premiere on October 26.
Adele follows Jack White and Alicia Keys, who provided the theme to Quantum Of Solace, while Chris Cornell voiced Craig's first 007 performance, Casino Royale.
Other notable Bond theme singers include Lulu, Sir Tom Jones and Dame Shirley Bassey, as well as A-Ha and Duran Duran.
