Celine isn't pop. My Heart Will Go On is considered the corniest song ever written. The fact it ******* means Celine Dion was an anomaly for a classical female artist.
Celine was at an disadvantage during the dawn of the 20th century because her voice isn't suited for rnb, dance pop, hip hop, rap or jazz but All The Way: A Decade of Hits still sold 16m copies.
Let's not even get into the fact that Celine rarely leaves Las Vegas for tours and still she's raking on those 200M grossing tour.
