I download lots of podcasts, see http://www.gocek.org/podcasts/ . Here are a few updates.
I struggled for a over a year to scrape the WNYC "New Sounds" home page until it finally stopped providing MP3s altogether. However, the "Soundcheck" podcast is related, so I am checking it out.
Taylor Strecker was the longtime host of the Sirius/XM satellite radio show, "Wake Up With Taylor", sponsored originally by Cosmopolitan Magazine, later just a daily radio show. I am not in the targeted demographic for this show, but I turned it on once in a while. This show was never offered as a podcast. The show was unceremoniously canceled by SXM at the end of 2017, but Taylor has started a podcast, "Taste of Taylor". The complete show is offered as a premium product, and excerpts are available at http://tasteoftaylor.libsyn.com/rss .
The Isabella Stewart Gardner Museum in Boston has provided MP3s for a fantastic, monthly, live chamber music series, but the last upload was in February, 2018. I am holding out hope. See https://www.gardnermuseum.org/experience/music .
