I've been doing the c25k so I make my own mixes for when I switch from walking to running and I found the thing that has kept me going is my music, it's very very important for me!
Some tracks that I love:
"Viva la Vida" - Coldplay
"The B*tch is Back" - Elton John
"Bounce That" - Girl Talk (if you haven't heard of Girl Talk, he's this DJ that mashes up all different kinds of music into kind of club music, really upbeat and makes you want to move and dance

)
"Mother We Just Can't Get Enough" - New Radicals
"Digital Love" - Daft Punk
"Band of Gold" - Freda Payne
"Roll with the Changes" - REO Speedwagon
"You're the Voice" - John Farham
I have a wide range of taste when it comes to music so anything that sounds even slightly motivating works for me! Post more songs everyone I need a new playlist for next week lol!
