Guilty pleasure lyrics abound in "pop" music. My two favorites:
"Someone left the cake out in the rain. I don't think that I can take it, 'cause it took so long to bake it, and I'll never have that recipe again!" MacArthur Park -- Diana Ross (her rendition is the best)
"Don't you know my tears will burn the pillow? Set this place on fire 'cause I'm tired of your lies. You were the one who left me neglected (I'm so sorry!) Apology not accepted, add me to the broken hearts you've collected!" All Cried Out -- Lisa Lisa & Cult Jam
As for musicals: "There are bridges you cross you didn't know you crossed until you've crossed." Kristin's delivery of this line on the Wicked recording just makes it more fantastic because she seems so into it (and obviously sounds terrific).
also from Wicked: "Yes?" "Uh, Nessa, I've got something to confess, a..." from the dance scene
and also "frank analysis" rhyming with "personality dialysis"...and "pal, a sister"
basically...Wicked is a treasure trove of guilty pleasure lyrics (because I kind of love them but they're not good)
"Contentment, it seems, simply happens. It appears accompanied by no bravos and no tears."
