March 23: It’s 31 Days of Free Music month at Podcasting News. Every day in March, we’re going to do our best to hook you up a great free music podcast.

We’re still on our way back from the Corporate Podcast Summit. We’re spending some unplanned time in Detroit, thanks to Northwest Airlines cancelling our flight back home.

While we were in London, though, we had a chance to talk with Indiefeed’s Chris MacDonald about his podcast, his two-terabyte Mac mini media center and a deal that he’s working on that may offer indie artists some high-profile exposure.

Chris’s podcast, IndieFeed, is a great example of how people are using podcasting to do new things, not just radio shows for the Internet. Each IndieFeed podcast episode features one song from an indie musician. There are podcast feeds for several different categories, like Electronica, Hip-Hop and Indie-Pop, so that you can subscribe and just get the types of music that you’re interested in.

While it’s not a traditional radio-style “show”, it’s a great example of how you can use podcasting to do new things, and it’s a great way to find about new music.

You can preview an example of an IndieFeed “episode” below, or subscribe to the podcast using one of the feeds at the IndieFeed site.
