Sometimes, the integrity of a good tune turns out to be more important (to the songwriter, anyway) than hearing the words clearly.
Examples:
From 1961: Patsy Cline’s “I Fall to Pieces” sounds like “I Fall, Toopy Says”. I don’t know who Toopy is.
Moving to the 70s: ELO called their song “Strange Magic”, but the way the notes are accented turns it into a “Strange, Mad Jick” - again not sure what a Jick is.
Got any more? And, optionally, do you agree with the songwriter that a particular mangled lyric was worth it in return for maintaining the tune?
Tori Amos. Just about everything she did up until about a decade and a half ago had at least some singing that was [del]unintelligible[/del] shall we say, artistic.
Granted, those are kind of extreme examples. Some of her material is more conventional. She is a musician first and often uses her voice like another instrument that pulls the words along with it.
The poster child for the category is the US national anthem. THUBbombs bursting in air and so forth. The lyrics were superimposed on an old drinking song. They don’t fit it very well. Hoozebrawd stripes and bright stars. UVVVthuh brave. Yeesh.

“sheep” by Pink Floyd might be a suitable example for this.
At this pointthe word “away” blends into a synth note (or whatever the hell it was those crazy kids were using). The same trick is repeated for the last word of each verse.
