Show Music

It is your podcast, so do what you want. I prefer something short. Maybe you'll eventually come up with one ending to record and use for every show. Whatever you do can be skipped by those not interested.

I find the endings funny most of the time.  You could just make a regular ending that you can use whenever you don't have anything else to play.  If you ever get a creative streak and you come up with something good, then you can play that at the end instead.

    Try doing Richard Stahlman's Free Software Song sometime.  I heard it on the first episode of LugRadio and broke out laughing while listening to it.  They also played his version, one that was sort-of hip-hop and a heavy metal version.  You should listen to that episode sometime.  I think you'ld break out laughing listening to it like I do everytime I listen to it.
