Listen to the producer's brand new round-up of songs form the last twelve months.

Rihanna, Lady Gaga and Bruno Mars are among the music stars who feature in a new mash-up of songs released this year.

The super-track, which has been put together by DJ Earworm, includes the top 25 songs of 2011 in the US.

Other artists and songs include Adele's 'Rolling In The Deep', LMFAO's 'Party Rock Anthem' and 'Firework' by Katy Perry.

The song features snippets of three tracks by RIhanna: 'S&M' and the more recent single 'We Found Love'.

DJ Earworm said the list was compiled using Billboard's weekly countdowns rather than their end of year chart.
