What other top-flight pair has produced so many hit collabos in the past 15-20 years? They've got 9 songs together, enough to fill their own CD:
'03 Bonnie & Clyde Crazy in Love That's How You Like It Deja Vu Upgrade U Hollywood Lift Off Part II (On the Run) Drunk in Love
That's not at all at the same level as Marvin & Tammi's 12 singles & 3 albums, but hey. I didn't say the comparison was exact. All I'm saying is that they're the most reliable "urban" duet partners of the last decade.
