Many Haitians are still struggling after the devastating earthquake of January 2010 and the charity-driven remake of K’naan’s “Wavin’ Flag”— featuring 50 Canadian artists, including Justin Bieber, Avril Lavigne, Drake and Nelly Furtado — is still $1.29 well spent. Released in 2010 under Young Artists For Haiti, the artists, Apple and the record labels all donate their share of the proceeds to charities Free The Children, World Vision and War Child to distribute to Haitian relief efforts. — K.B.
