Ok guys, I really like the idea of this thread, I might need some education on that subject. I've discovered that Pink Floyd was pretended to be prog, I didn't knew, but I like them so...
I also like Phill Collins and what he composed with Genesis.
So here's my "entry":

I'm still unsure if this is really prog, but it is some kind of rock, maybe more pop rock, so don't blame me. And even if it doesn't fit here, I hope you'll agree with me that the part at 3:55 is just fucking amazing.
EDIT: Hmm, after listening to some entries, I guess this obviously isn't any prog rock, hope you like it though.
EDIT2: This one better? --->
