Download the free app and listen to NHK WORLD RADIO JAPAN stream live radio and audio clips in 17 languages on your Android device, including Korean: https://play.google.com/store/apps/details?id=jp.or.nhk.nhkworld.radio.japan.android
What’s great about this app is the complete news scripts in Korean are provided and you can listen the news being read by native announcers at normal speed (which is very fast, even faster than the listening section of TOPIK II).
The news are from NHK World Radio Japan so basically they are Japan-related news, from Japan’s point of view, and mostly about politics. Or in other words, what Japan wants to say to the world.
By the way, the Indonesian language section is great if you’re learning Indonesian on advanced level. (I’m Indonesian).
You can also get the news script and audio on the webpage: http://www3.nhk.or.jp/nhkworld/korean/top/news.html
