Already a smash in clubs, with few knowing the source, the secret’s now out and the track is available to all.

It’s the first new solo stuff since Jamie’s 2015 debut album In Colour, and comes hot on the heels of his recent collaboration with Headie One and Fred Again.

Here’s a brief taste of Idontknow:
