Jobs was also a huge music lover and had strong opinions for how he wanted to listen to music.
I could imagine him in a meeting with music executives convincing them of his vision quite easily.
As I recall he also was the driving force behind convincing the Beatles to put their music on digital services. I think I remember when that was an iTunes exclusive.
I remember Apple convinced Cingular to relinquish a lot of carrier control over to Apple for the original iPhone, as another example.
