It looks like an official version of the Sonic Runners Original Soundtrack is getting a physical CD release for September 2016. Although it seems strange how the game servers have ended. The soundtrack was first released on iTunes in 2015, but over two volumes. This version of the CD contains the whole soundtrack on a single CD. Rejoice!

01. Beyond The Speed Of…

02. Fly Away

The soundtrack to Sonic Runners has an upbeat kind of rock feel to it, composed by veteran Sonic musician Tomoya Ohtani, who is becoming more associated to the recent direction of Sonic music. He is well known for composing music to Sonic Colors and Sonic Lost World.
