When I'm learning a foreign language I like to listen to songs in this language and translate the lyrics. Thanks to this method I've always learnt many useful words and phrases. Sometimes a song gets stuck in my head so I repeat it in my mind over and over again, remembering the new words.
Aside from their memorable melodies, many songs have memorable stories in them as well. You simply have to follow the story and learn the vocabulary along the way. I thinks it's a great and easy way to learn foreign words!
What about you? Do you learn languages through music too?
