It's the button highlighted in yellow:
When you press it it will populate your playlist with all playable Galnet articles.
Ugh... GalNet Grind...
"Here's this week's top stories... Last week, these seven stations, listed one by one, in agonizing detail, were shut down due to thargoid junk.. blah blah blah... In other news, some CG completed, and there was much rejoicing. In other news, the other half of that same CG also completed successfully, and there was much rejoicing. Meanwhile, on the other side of the bubble, some NPC you'll never actually see in the game did something you were completely unaware of, and while it carries no actual in-game repercussions, except perhaps for spawning off three more similar articles, read in this same monotonous tone that'd you'd probably pay real money to replace, like you can your COVAS... blah blah blah, you'll hear all this again in about half an hour, as Last Week's Top Stories, but told in future tense, because this stuff is all static anyways."
You mean that GalNet audio?
Sure, it's better than reading it, but how much of it can you really listen to before you pop your canopy and jump, just to make it stop?
