I like this song because even though it is a sad song about getting hurt, they still manage to put a melody that makes it lively and interesting, for its inspiring lyrics especially, the video.
Guy Sebastian starts the song with calm, peaceful and light voice and with a low pitch, then on 0:13 Lupe Fiasco sing the chorus with intense and powerful voice and with a high pitch. The tempo of this song is moderate to fast. They start it with a moderate tempo until 0:32, when Guy Sebastian starts rapping, then going back and forth to moderate to fast. It has consonant harmony, with homophonic texture.
This song is a triple meter. The song starts with the piano, with only 1 key repeatedly playing, then on 0:14 base starts playing together with the piano, then on 0:37 drums starts playing with all the other instruments.
