Currently listening to Classic Metal Essentials playlist on Apple Music. It has all the usual suspects: Black Sabbath, Metallica, Iron Maiden, Megadeth, Dio, and so forth. In other words, classic metal songs that are not that extreme. Except the very last one that is Freezing Moon by Mayhem [itunes.apple.com]. It is indeed a classic (black metal song), but not necessarily in the eyes (or ears) of the majority of people who like the other songs on this list. Do I like it? Hell yeah! ?
