Music Side Project 2.0, a form musicians will be able to fill out to create and broadcast an RSS feed of their music -- currently in the works! I'm not sure how much people use mobile. I have a PWA of LNBeats and V4VMusic, and for listening to podcasts I generally use Curiocaster on my desktop or Podcast Guru when I'm on the go. You can see all the Podcasting 2.0 apps at NewPodcastApps.com
