You are in your kitchen. Cooking dinner. The radio is on. You might hum some of the songs but you are concentrating more on cutting the tomatoes. Fair enough! You've had a long day and can't wait to relax. Lalalala laaa ....uhh llaalaaalaaaa...raararara.
Yes, you are singing... and no you don`t care how it sounds... because you are enjoying that song. But actually, what is that song about? Have you ever listened to the lyrics? It`s really easy. Go to Google, type in the lyrics and the song title.
You will be surprised what you´ll find! Have fun finding the particular song that expresses exactly how you feel at the moment! For example, "Hello (Turn Your Radio On)" Shakespears Sister (1992)...
