Neptunes productions always seem static and simple - no melodic flourishes, just drum loops and two-note melodies. The great Neptunes stuff is elevated by performers like Kelis but completely dismal in the hands of a nonentity like Timberlake. Pharell always seems like a self-satisfied populist, the kind of guy who gets out a guitar at a house party and wants everyone to love when he plays naff covers.
Timbo's approach to rhythm, texture and melody is so singular. Aaliyah and Missy obv, but even the second-tier stuff with likes of Brandy and Tweet feel so much richer and exciting. Wildly inconsistent after the mid-00s but much higher peaks and nothing as wretched as Happy.
