This is what their description says about Roots Music:
Canadian Roots and folk music, is based on the longstanding music of various communities across Canada. These genres contain new music by that are not only a reflection of the strength of musical tradition in Canada, but also the growing popularity of the roots and folk music scene. Few countries can posses a musical scene with such diversity and longevity as Canada. Folk music in Canada, for example, is more popular now than in the 1960s, when it first came into the spotlight. Folk artists showcase music across clubs, festivals, and concerts across the country and have a strong network of independent music labels as well.
I wish I could just call up all of the Folk musicians, rather than their Top 10 or whatever!
