I wish someone would ask him that during the promotion of the album. Just a simple "After listening to Heavy, I couldn't help but remember you and the rest of the band totally shitting on pop music 2 years ago. What brought about this complete 180?"
I like THP, and I like Heavy and the clip of Sorry For Now that we have. I'm pretty certain I'm going to like this album as a whole as well. My only problem with this album cycle is Mike's own words 2 years ago when promoting THP. It's bothering me because, Mike's comments in 2014 coupled with Mike now saying he wouldn't call Heavy pop or mainstream, makes him seem a little hypocritical.
EDIT: I realize he was promoting the hard rock album they had just made, but he went out of his way to diss pop music when he didn't have to do that.
