Is the China Winter Olympics song too much like Frozen or should we just 'Let It Go'?

YouTube users have been posting mash-up videos to show the similarities

Beijing might have a lot to thank Disney's snow queen Elsa for, should suspicions that its Winter Olympics anthem copied Frozen prove well-founded.

"The Snow and Ice Dance" was one of 10 official tracks to help the Chinese capital win its bid to host the 2022 games last week, but the organising committee has now come under fire for allegedly plagiarising the hit animated movie's Oscar-winning song, "Let It Go".

The ballads are almost identical in length, tempo, melody and instrumental arrangement, with YouTube users posting mash-up videos of the two to highlight the similarities.

Both songs have the whole gentle but oh-so-empowering piano thing going on, which was first pointed out in an article by magazine Caijing that now seems to have been taken down.

Others, however, have defended Beijing's track, sung by Chinese singers Sun Nan and Tan Jing and written by composer Zhao Zhao, arguing that many musicians take inspiration from others and user the same "golden eight bars".

Meanwhile, the city has other problems to contend with, notably severe air pollution, human rights concerns and a worrying lack of real snow.

The Beijing Games organising committee has not yet responded to requests for comment on the copyright accusations, which China is no stranger to.

Recently, the country's movie The Autobots was found to be very similar to Disney Pixar's Cars, while production of counterfeit handbags and clothing is rife.

A sequel to Frozen, which grossed more than $1.3 billion at the global box office, is in the pipeline.
