Switches from podcast to random, unfamiliar music

Every so often, my podcast will stop and a song I've never heard before will begin to play.  I haven't used Spotify for music in ages, let alone the genre of the songs that begin to play. 

This has happened when the player is minimized, the cat is nowhere near the keyboard, and I haven't touched a thing.

I also noticed that a handful of songs had been added to my favourites on 5/29/19, as well as 13 playlists. The playlists contain songs added between March and June of this year.  The songs that have interrupted my podcasts do not appear on the playlists or among the favourites.

I need to find a fix. This is happening when my young children are listening to a podcast before bed.
