It's too bad people couldn't maintain interest after The Emancipation of Mimi, but a year after Say Something came out Rhianna created new competition
for all the older pop stars, so there you have it. We now have the "Rhianna Model" that the record industry goes by which is why E=MC2 didn't do
very well.
I couldn't understand how American Idiot was a "comeback album", but whatever. Green Day had been doing steadily on Alternative Rock radio up
until that time, American Idiot and Wake Me Up When September Ends just gave them two more pop hits.
