Nowhere Fast and There is a light that will never go out by The Smiths
Neither of them are particularly "fuck you" but they still suit my mood upon locking myself in a closet after a breakup

mainly because the guy wrote it so his ex, the cello player in his band, would have to be there to record it and sing the harmonies for his lyrics about how much she sucked and how terrible she is. XDD
