Glitter is also a soundtrack and not a regular lp. "TEOM", >>>>> All of Beyonce's albums............. PERIOD............... And thats not even Mariah's biggest selling album..... Wow the greatness........... Lol Beyonce has only sold around 27 mil ww, that is not that impressive, she had everything in her favor. Heck even Rihanna is gaining more steam than her on a ww level. Mariah is the most important female artist of the last 20yrs. Bar none. Her success makes these other chicks look like light weights. Ho dare you compare her to Beyonce's meager sales.
