Talk about an incredible feat. 

As we head into 2020, Mariah Carey becomes the first artist to have a No. 1 song on Billboard's Hot 100 list in four different decades, according to Billboard.

The song? The timeless "All I Want For Christmas is You."

Carey's song was released in 1994 and spent time in the number one spot in the 90's, the 2000's, the 2010's and now the 2020's. The song first topped charts dated Dec. 21 and is now in its third week at the top for Billboard's latest Hot 100 list, dated Jan 4. 2020.

The song's ability to stand the test of time comes right on the heels of the Grammy-winning artist celebrating its 25th anniversary.

Last week, Carey released a star-studded music video for "All I Want For Christmas is You" to celebrate the milestone.

The video includes home videos from the Kardashians, Laverne Cox and Tracee Ellis Ross and others singing along to "All I Want For Christmas is You." The music video ends with Carey's 8-year-old twins, Moroccan and Monroe, dancing.

Speaking with USA TODAY last month, Carey reflected on her song reaching the 25-year milestone.

"It's so funny, somebody was just asking me, 'What were you doing 25 Christmases ago?' " Carey, 49, said. "I would probably say somebody was giving me a bottle and they were singing me a sweet lullaby Christmas tune. Because I was just 1 year old, so I don't know! 

"It's very much like I live in the land of the Tooth Fairy and Santa Claus," she said wryly. "I don't acknowledge time, I don't know what it is. I rebuke it!"
