Leona is a vocalist first and foremost..she is not a dance like beyonce who dances amazingly...for Leona to try and dance like that would inhibit her being able to sing live...Wherever Collide gets in the charts after the controversy it has had and late release of video etc it will have put leona back in peoples minds her album is meant to be amazing and by the sounds of glass heart which I love already, ..makes me laugh if Leona did a duet with adele would those haters then say Oh Adele shes boring or Leonas boring adele is hot?...some just hate on a voice thats kicks the shit out of her contempories...
