I can’t think of much if anything I’m aware of that I haven’t at least tried a track or two of. I’m genuinely curious, especially if an album is widely rated, and I’ll at least try it. As an example whenever someone is raving about something here I’ll go listen to a track on Youtube, so even if I only survive a few bars I have at least given it a go. There’s a lot of “classic albums” I’ve never listened to as I know the singles and they do nothing for me, e.g. pretty much any hard rock like AC/DC, Guns ‘N’ Roses, Van Halen etc. Just does nothing for me as a genre so why go further? Other stuff took a lot of effort to unlock, e.g. it took a very, very long time until I figured out why Trout Mask Replica was such a landmark. To be honest I suspect I had to venture to the outer reaches of jazz before that one fell into place, which is a long time given I first heard it in the late-70s or early-80s! There is loads of other stuff that is very highly rated that I have no real use for, e.g. Rolling Stones, Cream, Led Zeppelin, Abba, Queen etc. I can see it’s “good”, but it just doesn’t do anything for me.
