To be honest, I don't know if the fact she can only score a hit these days with a classic holiday song is something she should be proud about or want her lasting legacy to be. No one's been checking for new material from her for at least a decade, and she's never been a successful touring artist like Beyonce and Madonna.
But hey, at least she's guaranteed revenue each year with this song, so she can laugh all the way to the bank with it.
The funny thing is her former writing partner, Walter Afanasieff, who co-wrote/co-produced this song and most of Mariah's 90's hits continues to dispute many of Mariah's stories about the writing and development of this song.
