'Radioactive', 'Sex Yeah', 'Lonely Hearts Club' and 'Buy The Stars' are the additional tracks on the deluxe version of Marina & The Diamonds' forthcoming 'Electra Heart'.
The slightly more expensive alternative also includes the video for Top 30 smash 'Radioactive' and the yet-to-be-seen 'Primadonna' mini-movie.
