I wouldn’t say it’s weird as i’ve heard it in very old 70s vinyl and unfortunately had to throw them away. Ye olde PVC infection.
However, i just recently purchased the Cars original album on a 2016 re-issue. From front to back, both sides, there was the background PVC type woosh. Store suggested i clean it which i did. No dice.
Back she went and swapped it for Black Sabbath’s original 50th anniversary. Haven’t opened it and dropped the needle yet. Looking forward to it with fingers crossed.
