I think Whitney's. Not even Katy managed to do it. People just get too bored of one artist nowadays.

Whitney's. Doesn't Mariah still have most number one debuts?

MC has MANY MANY MANY

Song of the decade 2xx (One Sweet Day & We Belong Together

1st artist to have 5 consecutive no.1 hits

3 no.1 debuts on the Hot 100, the most for ANY artist (Fantasy, Honey & One Sweet Day)

The no.1 & 2 song on the hot 100 (We Belong Together & Shake It Off)

79 weeks spent at no.1 on the Hot 100 more then any artist in music HISTORY

Written 17 no1 hits more than any female in MUSIC HOSTORY!!!!!!!

The most no.1 hits for a SOLO aritst in the U.S

Mariah

Best selling teenage artist of all time

I voted for others. Britney's Opps and The Beatles #1 and #2 at the same week in Hot 100 are so hard to match Even Iggy was a featured artist to match The Beatles record

I'd say Michael's 5 #1 songs from one album record, which should be matched without a Kanye remix to bump a single to the top spot.

Other MJ records that are insanely hard to match:

Nobody will ever top Thriller's sales.

Nobody will ever have a more successful MV than Thriller.

Nobody will top Michael's official award count.

It's unlikely anyone's remix album will outsell Michael's BOTDF remix record.

It's unlikely someone (at least soon) will match Michael and Adele's record for the same top selling album two years running

It's almost impossible that anyone's MV will debut to the 500M people Michael's Black or White debuted to or higher.

It's unlikely anyone will top Michael's This Is It documentary as highest grossing music film.

Whitney's, easily!

It may be local and cop some shade, but Girls Aloud record for 21 consecutive singles hitting the top 10 in the UK , its in the Guinness Book of Records

Mariah's and Michael Jackson & Katy Perry's.Maybe the 69 weeks too.

Whitney's, tbh.

Mariah's 16-week reign on Hot 100 with "One Sweet Day"

dd brandy & Monica were coming for that wig

Whitney 's 7 consecutive Hot 100 #1s and it's not even debatable

Whitney's back-to-back #1s.

Gonna have to go with Whitney. Wasn't there a song in recent years close to beating Mariah's 16 week record? I'm THINK it was Black Eyed Peas or LMFAO, one of those two...

but I don't see anyone getting close to Whitney's 7 #1s. It just isn't happening anymore unless each one is promoted to the high heavens by all of the record labels combined

Whitney's, definitely
