It took a few months, but the new incarnation of If You Really Want to Hear About It now has a subscription component.
If you'd like to get notified whenever the site is updated with a new batch of songs, as well as receive liner notes, download links, and the occasional odd bonus, you can subscribe to the If You Really... email list. This seemed like the best compromise between a traditional podcast subscription and the more ephemeral approach I'm favoring with the current format. And I wanted to create a newsletter.
