Now starting the second block of 100 episodes, this one covers 20 examples of tracks from artists that only appeared once in the previous 100 episodes. Only a handful of tracks have been repeated on the podcast until last month's celebration. For this episode again, every track has appeared before - one as far back as the debut episode in 2016. To hear the countdown of 20 tracks, have a listen to The Sound Of Electricity Podcast episode 101.
