I did Week 3 Day 1 of C25K.
I used the podcast thingy. It was GREAT not having to time myself. The music was okay. Not my favorite, but not as horrible as I'd feared. I will probably only be able to use each podcast 2x instead of 3x because the music will grate on my nerves [there's one podcast per week of the program, so in theory you use each one 3x].
I am really picky about music, though. And the guy did it for free out of the goodness of his heart, so I'm kind of a lamer for even complaining about it.
