I admit to being a noob on navigating around the Tesla OS, but you have mentioned that people can listen to Ride the Lightning on their Tesla, but I have not been able to do that. If I call up a web page with the show, it won't play. Probably related to the Tesla OS not playing videos, it probably won't play audio over the internet (except through the TuneIn or Slacker app) either. I tried finding the show on TuneIn, but the Tesla app has no search function. I found it searching the TuneIn webpage, but they don't have it listed as Ride the Lightning, they call it "The Unofficial Tesla Podcast" or something like that. You might want to get that corrected with TuneIn.
There are a number of Tesla podcasts cropping up, Tesla should create a category in the TuneIn app for it.
Anyway, how to other people listen to this show in their Tesla?
