I get it. That was Boston for me for about ten years. I had to say "enough already" and couldn't switch away fast enough. Then one day I listened with "fresh ears" and appreciated what they did.
The thing with AC/DC is that a lot of the same songs get way overplayed and people write them off as playing the same three chords over and over. The deeper cuts defy that. Guitarists appreciate the power of what they play because it sounds so huge and its just a guitar and amps turned really loud.
But then you hear something like this (as a guitarist) and it is so mind blowingly good, fast and aggressive. It is a talent to play something that fast articulately without relying on a ton of distortion/gain/delay. A lot of these shredders from the 80's and modern day rely on a lot of gain and delay.
