 " Yo @-@ Yo " features 808 drums with a " dramatic " 1950s @-@ inspired pop " pastiche " . However , the 1950s concept " goes completely out of the window " for an " unhinged " bridge , which features a club mix which speeds up the drums featured in the song . The lyrics of the track discuss an uncertain relationship , leading to vulnerability , with Roberts describing it as a " dark " song . The song references a yo @-@ yo ; this is a metaphor for Roberts herself , a spinning yo @-@ yo " on the finger of a hot ' n ' cold lover " . Described as " confessional " by Robert Copsey of Digital Spy , the song has a " conversational " performance , and Roberts ' vocals were compared to that of singer Kate Bush .
