Kanye West is the biggest wave rider of the past 20 years because he only jumped on what was hot beginning with Graduation:
1) Toomp was a hot producer and he jumped on the wave when T.I.'s "What You Know About That" and Jeezy's "I Luv It" jumped off. Then Kanye was supposed to be featured on Jeezy's "I Get Money" produced by Toomp. This song eventually became "Can't Tell Me Nothin" which is why Jeezy's adlibs are on the song.
2) Timbaland was like the biggest producer at the time and Kanye had him redo the drums on "Stronger" and had him do programming on "Good Life" as well. This was all because he wanted something to compete with Timbo's "The Way I Are" in the clubs.
3) T-Pain. Of course, T-Pain was featured on "Good Life". Then he consulted T-Pain for the auto tune for 808's & Heartbreaks.
4) He wants to take credit for Weeknd when Kanye wasn't even making Progressive R&B. You could trace Weeknd's sound back to Ginuwine's The Bachelor album.
5) Kanye himself admits to Futuresex/Lovesounds bybJustin Timberlake influencing the sound of Graduation.
