Here is an article talking about the glorious debut of American Idiot on Canada's Charts.
"The first single from the forthcoming CD by the band Green Day hits Canadian radio and the charts in record setting fashion. The single "American Idiot" debuted at number four on the Nielson Radio Airplay Charts. "American Idiot: is the highest debuting single in the history of the charts. The record breaking debut is quite an accomplishment for any band but especially for a non-Canadian band since Canadian radio limits airplay of artists outside of Canada."
