I have no problem with people misunderstanding most of these lyrics. The few times I've listened to many 'popular' vocals, I've been confused all too often. Many times, it's an accent that hides the words, sometimes it's a loud/distorted instrument, sometimes the speed of delivery. Mind you, I am not even touching on what is called "Rap!" That's a completely different animal, in, as far as I can tell, a completely different language and delivery. Most of it sounds like a poorly written poem set to several sets of garbage can lids along with a broken phonograph player.
Amazingly often, the easiest to understand singers in English are actually those that grew up with another primary language (French, German, Spanish, etc.). Arguably, all those are from the same roots as English but their common usage is usually way beyond my understanding.
Well, other than "Volkswagen" and "Hey?!"
It just reminds me of the old parlor game of telling one person in the circle a sentence and having each person, in turn, repeat that to the next. The last person's understanding of what s/he was told is usually pretty far from the initial sentence. BTW, anyone here ever used the word "parlor" lately?!
No matter who we listen to, our brain tries to interpret the sounds we hear into words we have already become acquainted. Even if it's some bizarre combination such as "Chicken tikka!"
Wonder what some Russians or Iranians might have thought the original words were?!
