Trouble Is a Friend is a song by Australian singer Lenka Kripac, and it came out in 2008. Lenka continues with her happy and inspiring (鼓舞人心的) style in this song, using a bright and light melody (旋律). She also has interesting ideas about trouble – trouble grows as we grow and always finds us. Since we can’t make it go away, she says we should try to take it and learn from it.
