Normally only listen to the draft show from Dallas Cowboys site but it is not on yet so have to wait.
Something that I recently got back into is audio books when I am at work and am doing various computer stuff and have time where I am not verbally interacting with someone.
You can find a bunch of free audio books on YouTube. Right now I have been listening to older Dean Koontz books. And if you have a tablet or phone with enough space you can download most YouTube vids and watch, or in this case listen, to them if you are off line or away from wifi so you don't waste your minutes.
