Aren't both audio stuff where you press play, pause, stop, rewind and fast forward?
The only difference I can think of is that you might sometimes want to accelerate playback of podcasts but that doesn't mean it can't exist in the same player.
Podcast apps, good ones, have many features you don't need in a simple app like a winamp or vlc.
1) An online catalog of series that is searchable (probably both by name and topic and participants).
2) That catalog must contain metadata both at a series level and an episode level.
3) That online catalog must also be navigable without search, of course.
4) Ability to subscribe to any given series and for the app to have an option to pre-cache an episode for offline use.
5) Several content controls that aren't really required for music listening but are must haves for podcasts such as timed skips (30s, 60s) and playback speed adjustment (only useful in a music player where you probably want to do beat matching).
I think the biggest differentiator though is the episode/series catalog. It makes podcasts actually discoverable.
There are audio players that allows you to find radios by various criterias: genre, bitrates, location, etc.
I don't think it is hard in term of UI nor does it justify a different app when you can have an additionnal tab that allows to find podcast. You just have to change the criterias.
Subscription to podcast is done via rss right? I don't think that is a huge deal either.
