Why 10ccs Im Not in Love was never played for slow dancing on Dance Party USA

Im Not in Love was originally a song by the British band 10CC and it became a huge hit in 1975, shooting at, 1 on the UK music charts. In a way, it still is the ultimate slow dance you find on every classic love song compilation but very few people ever noticed the very cynical and harsh lyrics. The boy in the song may pretend hes not in love when he probably is, the way he addresses his girlfriend is quite dreadful and mysogynist, making it the perfect song for Tori to sing from a female standpoint. Indeed, to prove the girl hes not into her, the singer tells her : I keep your picture upon the wall, it hides a nasty stain still lying there, clearly treating her like an object of both desire and disdain.
