Turning podcasts into normal MP3

[itsnowornever]

Here's my issue-

I am running a Nike+ that is being PICKY! I only listen to techno podcasts when I run (seems like the podcasts are the only good ones...the download-able "music" stinks) however, Nike+ wants to only play MUSIC not podcasts in the background...tried putting the podcast in a playlist (which worked) to see if that would work, but it wont. Tried burning the podcast to a CD and then pulling it back into iTunes to see if it would become "normal" music again...and it didn't. Still read it as a pod cast.

How do I change that? Can I change that?
