True, though that blog post also says "We do not crawl or scrape websites to source these lyrics.", which was definitely not true (though may be now).

Google licenses the lyrics through a third party, LyricFind, which in turn hired people to transcribe them. In a small percentage of cases, those transcribers did not do their own work and instead copied lyrics from Genius.

I think it was true then. I believe their claim was usage via third party?
