I should not even bother to say anything to you since your status already says it all: STUPID. But since you've been talking about how successful Avril is in the US and Britney's single were such flops, pointing out especially 'Someday' and 'Do Something', here's something for you: those songs were NEVER released as official singles in the US, and neither had adds date on the radio. So get your facts straight before you come in here, a Britney thread, to say anything.
As for Lavigne, stop trying to hide her ****** runs on the singles chart by calling all her 4th singles not official or promotional only. They had airplay release dates and they were released during the DIGITAL era, so if they didn't chart or they charted low, it's because they were indeed flops. Deal with it and accept the fact that Avril isn't praised by the radio as she was when she debuted in 2002.
P.S.: Don't even mention Britney's singles from her 3rd album era. Anyone who's not biased knows what happened back then. And I won't talk about Amy/Hot cause that would be too humilliating for you.
