Which GPL for Ogg Frog?

[Rippit the Ogg Frog <rippit@oggfrog.com>]

I am working on an audio application called Ogg Frog 
(http://www.oggfrog.com/).  It is not released yet, but I hope to 
release the first version later this fall.

I am having trouble deciding which version of the GPL I will release it 
under.  It has two GPL dependencies so far, libmad and libid3tag, which 
are both GPLv2 or later, so I could choose to release Ogg Frog under 
either GPLv2 or GPLv3.

I have read many of the arguments over GPLv3, and tried to weigh their 
merits, but I'm afraid they all just make my head spin.

I have always been uncomfortable with the "or, at your option, any later 
version" in GPL license notices.  It is most likely that if I choose 
GPLv3, I will require that specific version and not allow any later version.

Is there a web page somewhere that distills the essence of each of the 
arguments, pro and con?  I've tried to read some of the threads and 
Debian legal, but I'm afraid I haven't been able to reach a conclusion 
by doing so.

Thanks for any advice you can give me.

  Software isn't the only thing that should be free.
        Music should be too, as it once was.
