Shaken Udder is giving consumers the chance to get free downloads from eMusic as part of its on-going commitment to the music scene.

Shaken Udder – which launched at festivals back in 2004 – has teamed up with music download website eMusic to offer its customers 35 free downloads when they buy a bottle of Shaken Udder milkshake.

The on-pack promotion, which will run from December until February 2012, is a new venture for the small firm which only launched its premium milkshakes into Sainsbury's and Tesco stores during the summer.

Founder, Jodie Farran, says: “It's great to be able to run a promotion that ties in so well with our greatest loves: milkshake and music!

“We know we have a really loyal following of music fans so I'm hoping the free downloads will entice them to buy even more bottles of Shaken Udder during the winter months.”

Promotional packs, which also feature new branding that shows the trademark Funky Cow listening to music through headphones, will be available in-store from early December.

Shaken Udder milkshakes are available from Waitrose, Tesco, Sainsbury's, Ocado,regional Co-op stores and Selfridges.
