There very few matches made in heaven, among the ones I really relate to these's ; LeBron and Wade, Pounded yam and Vegitable, Butna and Leri Q, Uninjured prime Ribery and Robben,
Plantsin with other food etc. High up there we have Timberland & Timberlake. Them working together guarantees eargasims. I wouldn't know where to start if I were to begin mentioning the hits they've made together, I'll just say they go as far back as "Cry Me A River".
The song in my opinion should have been released as a single, maybe because of the length it couldn't have but it could have amassed a lot more commercial acclaim. It actually didn't perform so well for Justin Timberlakes standards selling under 100,000 copies and it ever made it into the Billboard charts.
Also, there was a lot going on in the song and that's usually a recipe for disater. Considering it was a blend of salsa, pop, african elements, hip hop, classical music and some other contrasting elements but for some reason that wasn't the case on this song. It was well blended and I feel the transitions really helped with a lot of it. I'm going to chip in that James Fauntleroy credited for co-writing the song (specifically for you YJ)
