Regarding rock's popularity... I saw a list of the best selling heavy rock albums from the first half of 2017 in the US today. FIVE of the ten spots are Metallica. In case any of you guys are wondering why rock music is not all that much in touch with popular culture anymore and not as influential as it used to be: Well, it's a retro show it seems.

Of course, there's still great new rock music out there, but it's just not as culturally relevant as it used to be. And no, bands like Imagine Dragons don't rock hard.
