Correction @Mark 111 Mariah didn't make Rappers popular on pop music she was doing what everyone has already done before.& here's the list.

Blondie Rapture Ft. Kurtis Blow year 1982 first time when Rap/Hip Hop was introduced to Pop music making it a much more broader horizon for other acts to infuse Rap/Hip-Hop together due to the popularity and success of Rapture.

Aerosmith was the first Rock Band to infuse Rap/Hip-Hop together with there remake of their own Song Walk this way which came out in the 70's they reintroduced Walk this way by adding Run D.M.C back 1984 heightening Rap/Hip-Hop popularity and success. Now the continuation of Rap/Hip-Hop broaden even more with Janet Jackson she infused Rap/Hip-Hop together with R&B.
With the success of Alright she remixed it adding unknown Act Heavy D making Alright an even greater success which made Janet Jackson to be the one whom made adding Rap/Hip-hop popular so instead of using it one time and one time only like Debbie Harry from Blondie and Aerosmith Janet use it many times over with songs like
Janet Jackson W/Mc Lyte You want this 1993
Janet Jackson W/Chuck D(of Public Enemy) A New Agenda 1993
Janet Jackson W/Q-Tip Got till it's Gon 1997
Janet Jackson W/Busta Rhymes What's it gonna be 1999
Janet Jackson Son of a Gun remix With Missy Elliot P.1 & P.2 was made with Missy and Puff Daddy(before he became P. Diddy) 2001
Janet Jackson W/Kanye West My Baby 2004
Janet Jackson W/Jermaine Dupri & Khia So Excited 2006
Janet Jackson Call on Me 2006
So Janet was the main one who made it popular
Many others followed suit Mary J. Blige countless Rap/Hip-Hop Artist even Whitney Houston did a remix of My Name is not Susan W/Monie Love back in 1992 so if your gonna created anyone for Making Hip-Hop/Rap popular it was Janet not Mariah,Mariah just followed in Janet's footsteps in what she had already made popular just like Blondie and Aerosmith, I rest my case glad to give you knowledge on the infusion and popularity of Rap/Hip-Hop and who really continued to make it popular.
