Avicii and Robbie Williams have teamed up on new single 'The Days'.

The track will serve as the lead single from Avicii's upcoming second album Stories, which is set for release in 2015.

Stories will serve as the follow-up to Avicii's debut album True, which has now sold over 5 million copies worldwide since its release in September 2013.

Earlier this month, the Swedish DJ cancelled all forthcoming live shows due to health concerns.
