UNV also offered a CD with 27 songs in nine languages, by musicians from 18 countries, in celebration of IYV. The CD featured Jamaican reggae star Tony Rebel, who donated the song, "Not all about money", and Portugal's Paulo de Carvalho, who donated the song "Vai e faz" (Go and Do). Most of the songs praised the virtues of volunteers, but the last song, by Dave Greenfield of Canada, was meant to provoke political debate and question social issues about volunteers.[22]
