I often said you probably only need 1 AC/DC album (dons tin hat).
Get in! Yep, LZ fanboy. Surprising really as I didn’t ’get them’ until ‘76, when they were almost done, I was a Purple guy (whom I now can’t stand, along with other performers from that time in my life that I adored, I'm looking at you EC).
PR play sooo much Queen, who, IMO, weren’t particularly ‘rock’ post Sheer Heart Attack. I do wonder if Sabbath would have finished so high, were it not for Ozzy’s demise; we’ll never know.
Finally, big thanks to @rwillett for doing the spreadsheet, donkey work on this, most appreciated.
