Easy Languages is an entirely YouTube based video series that gets you learning the language the way its actually spoken on the streets! Be it Paris, Munich, Rome or Toyko, you'll hear real people being interviewed on a variety of topics. It's great for picking up vocabulary and good for training your ears to listen to the language in its natural flow. The subtitles are in both the target language and English which helps your listening skills. I watch the same video a few times to really take in the conversation.
