You might have heard of a popular conspiracy theory about one of Canada's most famous rock stars. Avril Lavigne died in 2003, and her record label secretly replaced her with a body double who has been living as an impostor ever since. 

Could it be true? Probably not, but comedian Joanne McNally helps us find out on the new podcast Who Replaced Avril Lavigne. 

Plus, a lot of people think history is boring. Depending on how you were taught, that's pretty understandable. Simply memorizing a bunch of dates or names can make history feel about as dead as that fourth prime minister (whose name you've already forgotten).

To Simone Polanen, the opposite is true– history is all around us, woven into the fabric of everyday life. Simone joins us to talk about her podcasts Past Perfect, a history trivia show, and Not Past It, a story-driven show about the links between the past and the present.

All that and more of this month's top picks, this week on Podcast Playlist.
