I have two:
"Love gets what it wants, love gets what it deserves" – Nervous Young Inhumans by Car Seat Headrest (it actually says "art" instead of "love")
"And when the lights all went out, we watched the lights on the screen" – Disenchanted by My Chemical Romance (which really goes "our lives on the screen")
The way I heard them just means more to me personally than what I found it out to be. Been wondering if anyone has any similar examples from their own mishearings!
