Best running app to use with Zombies Run

I love this app. I was able to erase all the music on my phone and free up space because with this app I dont need my own music. The mixes are so great that they keep me running and I am running farther and faster. I use it with my Zombies Run app for a complete story and music experience and I havent found anything better in the market.
