Two mates of mine are running a half marathon (for the NSPCC) and it got me to thinking what would be the best way of listening to things like Spotify and Audible while running? I listen on my phone but that's hardly small and lightweight. I see a lot of talk about MP3 players, but not so much for streaming. Both Spotify and Audible have the ability to download but I'm not sure if they can download to an MP3 player. Any assistance would be appreciated oh techy people.
