A music quiz show hosted by Marvin and Rochelle Humes, in which pairs of contestants are tasked with naming as many hit songs and artists as possible under time pressure. The contestants hear a short audio clip, and from this they must determine the correct answer. The player with the quickest reaction time gains victory. This is a true test of music knowledge, and a variety of contestants step up to the challenge. After three rounds, one contestant is able to play for a £10,000 grand prize.
