I got this article from "google+", I will follow it and hope to improve my English.
* Choose an English song with lyrics that you can hear clearly (preferably one that you haven’t heard before).
* Listen to the song with your eyes closed and try to work out the theme of the song from the lyrics and the expression in the singer’s voice (is the song about love? Has the singer been hurt? Is the singer happy?)
* At this stage, you could listen to the song again and write down any words or phrases that you hear (whether you understand them or not).
* Find the lyrics online (type the song name and artist into Google and you should be able to find the lyrics easily).
