I have to listen to something, usually music, when I walk. I have a newer phone that lets me listen to Pandora radio. But I also listen to "100 A State Of Trance Tunes" that I purchased from Amazon.com. I used to listen to a satellite radio station that played that kind of music but they took that away. This music has a very good beat to it and most songs are upbeat. I really do tend to walk faster and like walking better when I am listening to them. I do sometimes listen to some books from Audible.com but I don't really walk as fast then. Beatport.com is another place to purchase music from and I have a couple of songs from there, my favorite being Fingerpaint(ing) by Digital Witchcraft. Music really keeps me moving and I would be really slow, and unmotivated, without it.
