Canadian rapper Snow, best known for his 1993 No. 1 hit “Informer,” suffered a great loss when his wife, Tamei, passed away suddenly of cancer in 2009. In her honour, he has released a charity single, “Shame,” featuring reggae legend Mykal Rose (Black Uhuru), and 100 percent of the proceeds go to the Karen E. Mumford Cancer Foundation (KEM). The non-profit provides financial assistance to cancer patients and helps broaden awareness of the disease. Produced by Kent Jones and Cool & Dre, the song, however, isn’t about cancer, rather it explains why he disappeared from the music scene in the U.S. following “Informer.” Buy it here. — Karen Bliss
