I make mixes mainly for myself. I get EDM I like and set it to 128BPM so I can walk the streets for exercise and fitness. It's great on the cross trainer at the gym, and especially on a treadmill at a 3% incline. Awesome for people like me with dodgy joints. I also make mixes for chilling, background music or when you're stuck in traffic. The Roofgarden series is good for that too.more
