Is it possible to download an entire playlist suitable for 30-45 minutes of aerobic exercise? I need a change as the Rolling Stones at 6am is starting to get a bit old and I cannot stand indoor rowing in silence. If not, can anyone share their list or suggest some tracks so that I can then go and buy the songs myself? I'm using an ipod nano, so I assume that anything in podcast or itune form will be easy to me to get.
