If It's Over
Featuring a mix of upbeat dance pop and tearjerker balladry, Emotions was one of the biggest albums of 1991. Carey's vocal pyrotechnics were pushed to the front of almost every song, an obnoxious thing to do at the time. But hearing her dog-whistle register now is kind of amazing. That sound may stand as the definitive nostalgia-inducer on future oldies radio.
