Hi fellow C25Kers. I'm looking for advice about the best way to store/play music when running. I have an 8GB iPhone and use iTunes Match to store all my music in the cloud but have downloaded about 100 tracks to my phone for running. I'm getting a bit bored with the same songs but have used all my storage. What would you recommend I do to not use too much storage on my phone but also not use too much data either?!!
