On 'Dynamite', vocoder enthusiast Taio Cruz indulges in the tired and now sadly obligatory "ay-oh" refrain that graces every second r'n'b album. Elsewhere, it boasts a sizeable hook, but this is by far the worst tune on Brit rapper Cruz's patchy sophomore album Rokstarr, and twice as grating as harmless earlier hits like 'Dirty Picture' and 'Come On Girl'.
