I agree.
I just think it has been a while since we've had a great Pop/Rap combination. It's such an over-commercialized concept at this point that there's really no thought put into the music and building a song from the ground up to support it. Most of the time, one of two things is happening:
a) An already-complete song by a new-to-the-scene singer has a feature thrown in by an established rapper to give the song cred.
b) An already-complete song by a new-to-the-scene rapper has a featured thrown in by an established singer to give the song cred.
But really thinking about it, none of this really takes into account whether or not the feature actually makes the song
better.
When I think of great singer/rapper duos on songs, of COURSE my fave comes to mind. Christina has a some great collabos that were ground-up concepts between two established acts, and not just pathetic attempts to "break" an artist:
Tilt Ya Head Back (with Nelly)
Car Wash (with Missy)
Tell Me (with Diddy...
)
Mariah Carey has also had some good ones over the years:
Breakdown (with Bone Thugs n Harmony)
Don't Stop [Funkin 4 Jamaica] (with Mystical)
Fantasy Remix (with Ol Dirty Bastard. "Me and Mariah, go back like babies and pacifiers." - Most iconic rap feature of all time, tbh)
EDIT: I guess I should also acknowledge "
Airplanes"...
