Actually, maybe not top 5. Top 10 for sure, though.
This is probably the only matter on Judas Priest against their favor I will disagree with you on.
If any song needs to be moved to the top 5 it's Angel of Death.
I actually think Angel of Death is the greatest metal song of all time. For a few reasons:
1) It's lyrical subject matter is heavy and super controversial even to this day. When video game executives won't let you put the song on Guitar Hero because of lyrical content even at the insistence of fucking Lars Ulrich, you know you've got something special. Making bigwig white collar movers-and-shakers uncomfortable because of ugly truths of humanity is what heavy metal is all about.
2) Singlehandedly set a new musical standard for thrash metal (much more so than Master of Puppets)
3) Is probably the only song from the last 25 years (MOP aside, duh) which could be claimed as "the greatest" which could be taken as a serious suggestion.
4) For my money is just as influential as anything by Sabbath, Maiden, Metallica.
and this is coming from someone who is very
critical of Slayer.
