With 13 weeks and counting at No. 1 on the Billboard Hot 100 chart, Mark Ronson and Bruno Mars' "Uptown Funk!" has entered an elite class of smashes that enjoyed the longest runs atop the chart in its 56-year history. Only a handful of songs have spent more time at the top of the Hot 100 chart since it was first introduced in 1958, and only a few more have been at No. 1 for 10 weeks or more.

If Ronson and Mars' collaboration spends at least one more week at No. 1, "Uptown Funk!" will join a list of six songs -- including the Black Eyed Peas' "I Gotta Feeling," Los Del Rio's "Macarena (Bayside Boys Mix)" and Whitney Houston's "I Will Always Love You" -- that have spent 14 weeks in the penthouse of the Hot 100. And if it logs three more weeks at No. 1, the current hit will tie Mariah Carey & Boyz II Men's "One Sweet Day" for the longest-leading Hot 100 No. 1 ever, at 16 weeks. Of course, "Uptown Funk!" would hold the title by itself if it makes it to 17 weeks at No. 1.

One title "Uptown Funk!" already holds? The longest run at No. 1 during this decade (so far). By surpassing the 12-week run of Robin Thicke's "Blurred Lines," Mars and Ronson can now claim that honor by themselves. Click here to view the Top 10 longest-running Hot 100 No. 1s of the 2010s.

What do you think of the chart dominance of "Uptown Funk!"? Will it continue its run into the Hot 100 record books?

We're witnessing history, omg. these upcoming weeks will be so exciting!

So many great songs

Hold on Mariah please!

MARIAH HOLD YOUR WIG TIGHT GURL

I don't want Mariah to lose her record but Uptown Funk deserves it

Mariah hold your wig for real sis

Boyz II Men are so underrated

They got caught up on the the Britney Spears era

Boyz II Men

I know prior to the beginning of the "Rock Era" (which I unfortunately think has ended), there were songs that spent more than 16 weeks on Billboard's Top 100 Chart (pre-Hot 100). I know one stayed there for 17 weeks, because that was going to be "One Sweet Day's" next achievement if the song could have held on another week. As it is, the performance at the Grammy's/AMA's in 1996 (I can't remember which) gave the song enough of a boost to reach it's 16th week, and I'm surprised the Chart Watch person at the time couldn't correlate the performance with the boost to hang on. The boost only lasted one week, as it fell from #1 to #5 the next week. Hearing about the 17 week song from way back when is another reason I'd like UF to get 18 weeks.

A damn mess

I think she'll break the record again with her new singles or so, so I'm not too worried.

Wait.. Smooth by Santana came out in 2004?! I could of sworn it was from the 90's

It was 1999.

14 seems to be a big thing.

Hope it ends @ 15 weeks so it can bridge the gap between 14 weeks and 16 weeks.

So close
