This week on Podcast Playlist we're sharing new and notable podcasts for January, along with some interviews from the podcast world.

First: In 2016, Soleiman Faqiri was killed by guards at an Ontario jail. An inquest last month determined his death was a homicide, but the podcast Unascertained reached that conclusion more than two years ago. Leah sits down with host Yusuf Zine to talk about the case.

Then: Weight For It is a show that unpacks the nuanced thoughts of fat folks, and of anyone who worries about their weight. Host Ronald Young Jr. joins Leah to talk about body image and how we can challenge weight bias.

Plus: Boston's "Big Dig" was the most expensive highway project ever built in America. Construction lasted nearly two decades and the project ended up going billions of dollars over budget. But was it worth the outcome? Host Ian Coss of The Big Dig weighs in, and shares what this project can teach us about how to build better cities.
