Producer who gets far more recognition than those he collaborates with. ("Timbaland Feat. OneRepublic" should've been "OneRepublic Feat. Timbaland".)
SEI is most likely in my opinion. This is because he has this passion for music, and if you watch the OR video, you see him getting proper into it. He loves just immersing himself in his music. I imagine SEI as more likely than SLI because of his concern for what the music evokes.
Any other ideas?
