Nestlé hopes to serenade the musically-minded with a new £10m on-pack promotion for Kit Kat. Consumers can win free music downloads from the Kit Kat website, which will boast the entire back catalogue of UK record label Universal. Wrappers on 35 million Kit Kats and Kit Kat Chunky bars will run what is the third and final instalment of the brand's £24m 'Break' promotions for 2009.
