We wrote about the Nectar Music Store when it launched last year – it’s the digital music store of the UK-based Nectar loyalty scheme. It’s just announced a new promotion, offering an exclusive track from Alesha Dixon to its users for free. It ties in with a competition to either see and meet her when she supports Enrique Iglesias at The O2 in London (!), or get a private dance lesson from Alesha, who won the UK’s Strictly Come Dancing series a couple of years ago.It’s a big deal for Dixon, given the huge promotional muscle of Nectar, which has millions of UK customers. She spent much of last week climbing Mount Kilimanjaro for Comic Relief, so her profile is high at the moment, too.
