adidas has chosen Microsoft’s MixRadio as its new source of music for its miCoach Smart Run watch. There are over 34 million songs available in MixRadio’s catalogue and you can play those online. But to gain access to this you would need to sign up for a subscription. There is currently a six-month free access promo from adidas but you will get access to this if you download the over-the-air update for Smart Run, which you can access in the settings menu.
