As for the google search, I think you're giving too much weight to YouTube encomiums.  She may have left a posthumous cache of ghazals she wrote, and there may be recordings in her own voice of a few.  But she's certainly not a well-known or well-regarded ghazal singer.  As a general rule, I feel that if this factoid isn't even in her Wikipedia article, it shouldn't be included in other articles as if it were an established fact.
