3PP and a podcast about writing (it's in German) are the podcasts I like to listen to.
When I'm not in the mood for podcast or have a hard time focusing, I'm listening to a 1 hour piano song on Youtube calles "Music to write faster and better". It works great for me, although usually I'm drawing or typesetting while listening to it, and not writing.
Every time the song comes to an end, I can be proud to have worked for a whole hour.
When I'm doing stuff that doesn't take much concentration, I listen to the friends and family I call. So I'm on the phone while working.
Last week I started to re-view Vikings while working, but that was a lot of distraction. So I switched to re-hearing lessons from svs learn while working. That works great!
