What You Should NOT Do
Although it might seem tempting DO NOT use music and song lyrics to learn a foreign language. Most songs contain either a form of dialect, inappropriate slang or rude language. Many songs play with language by falsifying it and twisting it around. Some use very old-fashioned and poetry-style language. So don't use it.

Don't read German newspapers. Most of them are very political and use a terminology which is extremely hard to understand. The sentences are extremely long, so usually when you get to the end you cannot remember how it started. Newspapers are clearly for the advanced language learner. So please stay away from them in the beginning.
