Is The Metallica MasterClass Worth It?

MasterClass is an online subscription service that offers classes from top performers in about any field you can imagine. Now Metallica has a class that teaches us regular mortals "how to be a band." I didn't know this class existed until I heard an ad for it on satellite radio today during my coffee run. I was like "Whoa, that's cool" and made a mental note to check it out when I had some time today.

The trailer definitely looks interesting. I don't know if I would get anything out of the course because I am not in a band, but I suppose watching the videos would still be entertaining. I think MasterClass is $15 a month. I really don't need - or want - another monthly subscription charge, but I would be curious if anyone has done this course and their thoughts on the value.
