"Nothing Compares 2U" by Sinéad O'Connor
Taking a step back from the boy band saturated decade, check out every '90s girl's trademark break up song, Sinéad O'Connor's haunting "Nothing Compares 2U" (props for the futuristic IM talk!). We don't know a soul who can't help but sing along for the classic chorus, but be warned, only the brave should attempt that high B note!
