Understanding song lyrics

In literacy we have been learning about Michael jackson and Bruno Mars we listened two song's they were treasure by  Bruno Mars and man in the mirror by Michael jackson. we discussed and brainstormed the song's title meaning we then looked at the Lyrics and what they meant. Treasure by Bruno mars is about like he like the girl like a golden star then the second song man in the mirror by Michael jackson is about he want to changing  himself but he help the homeless kids by giving them food.
