Other than substance addiction issues, one might not think that Bon Scott and Amy Winehouse have much in common. However, both of them were involved to the point of obsession with people who were incredibly bad for them, and although musically speaking they are both artists I can't get enough of, I have to stop listening after a fairly brief period of time because I know what and who they're singing about and it's really depressing.
The other issue is the fact that I can relate all too well to being obsessed with a person who is really, really, really horrible for you. I did it more than once. People think that all-consuming "love" is wonderful. It's anything but, and usually, it isn't really love, it's an obsession. So, yanno, no thanks to ending up in the ER with bloody wrists over some asshole who doesn't deserve my pain. Better to be alone than to be with someone toxic.
Although, unfortunately, in my case, more often than not, I'm alone in bad company.
Plus, in the case of AC/DC, I can only listen for just so long (and that isn't long these days) before I start getting really pissed off about the way Malcolm Young went out. Dementia is the absolute fucking worst, particularly when it takes out someone whose intelligence was a key part of who they were. Malcolm Young was a high school dropout, but he was smarter than a lot of people with strings of letters behind their names.
The late Glen Campbell's wife said of dementia "It's better to die some other way," and she's absolutely right. Fuck dementia.
As Bob Seger once said, sometimes I wish I didn't know now what I didn't know then.
