App login?

Hi! I'm currently a college student with limited free time. I recently discovered Craig Ferguson's show and love it. I can't make the show on its air time and I read the app lets you listen later.

What I'm asking is, if it's possible to use someone's login. I do have a subscription to Sirius XM but can't afford extra for the app.

If not or there's some complication thy prevents that, I'll understand. I just wish to listen to the show. I have zero interest anything else else. Thank you.
