Oh, but I HAVE done exactly that, and frequently.
I wouldn’t really expect anyone to have paid that close attention to any of my music, but for example
in a tune I posted last year called “Baby You’re Real” I had the line, “You’re not a beauty little girl but hey you’re alright” which is a verbatim left from Springsteen’s “Thunder Road” (different melody, however)
in another tune called “Matter of Time” (which I’ve never actually recorded) I have the phrase, "But in the meantime, as we struggle through the lean times… “I’ll pick up my guitar an play!” – direct homage to the Who classic “Won’t Get Fooled Again”
I have a tune called “Who Tell Me Who” that has the phrase, “Tomorrow is the day that never knows” – direct allusion to the Beatles tune
I posted a Metal tune some years back that has the line “Like my soul, in desolation lies” which I stole from none other than Onkel. Even he didn’t catch it
And other instances I can’t recall
