I get your reasoning, but my friend Annie Munson who does the same genre started recording in 1989 but didn't make an album untill 1995, yet she says that her coreer started in 1989. i thought it'd be the same with deadmau5, but i do understand your reasoning. i can't find anything in the article other than the name of an album that acknowledges that he was active in 1998 at all. 199.101.61.190
