Podcasts are a good idea. I'm also a big fan of INTERNET RADIO through such apps/websites as "TuneIn" - it's good if you have handy access to wifi or a good data plan.

There are thousands upon thousands of real radio stations to choose from - from countries all over the world.

When you listen to "talk radio" stations, you're listening to real foreign language conversations, always new and fresh and available 24-hours.

You shouldn't use it as your only method of language learning. If you're studying the language through other methods, you'll find when you're listening to radio that you'll understand a little, and the more you listen you'll see that it reinforces what you've already learned and you'll eventually find that you can understand more and more of what you're hearing. When you're busy again, just switch it off; there's no need to go to the end of the lesson.

I usually listen to podcasts on my way to work/study. 

There's a lot to choose from.

It can help a lot with your listening skills.
