On his recent solo acoustic tour, Slipknot singer Corey Taylor spoke candidly about folks he doesn't much care for, among them Rick Rubin ("overrated") and Scott Weiland ("lazy"). It turns out he's equally vocal about people he likes, and in a Twitter post, he gushed about his collaboration with Dave Grohl and Butch Vig.

"HUGE checks off the Bucket List today," Taylor tweeted, revealing that he'd recorded a song with the Foo Fighters frontman and acclaimed alt-rock producer. "Do the words 'holy s---' say enough about it?!?"

As the NME reports, the former Nirvana drummer recently worked with '80s metal outfit Ratt on another new song, and it's likely the Taylor team-up is connected to the same Grohl side project, currently known as 'TBA.'

That begs the question, "What does Taylor thing of Ratt?"
