The first song is Elegy for the Artic by Ludovico Einaudi. The video is both beautiful and tragic. Please take a moment to watch it on YouTube. 

Track 2 is also by Ludovico Einaudi and possibly his most famous called Writing Poems. 

Track 3 - A Lama With No Name by Matija. I'm only listing this track here because I love the name of it. 

I'm sure you can find the other tracks by using Siri. But, if you cannot find a certain track, please email me at hello@andonia.com with the episode number and time stamp.  You can also send an email if you have a song or artist suggestion or even genre, and I'm happy to take on the challenge of remixing.
