Nah 03 was 50 Cent
06 was Jeezy
I can see your point though
Well are we talking about "buzz" or overall awareness, impact, sales when we say "most popular"
Becuase in 06 I'd say that Jay's comeback definitely overshadowed Jeezy. Nas outsold Jeezy first week in 06 and that's when Jeezy was promising "them first week numbers" would prove that Hip Hop wasn't dead.
Jay did 600k first week, had Show Me What You Got (hate that damn song) in CONSTANT radio rotation, and had one of the best marketing campaigns that I can remember. Jay was literally EVERYWHERE.
