The thing is, Bey doesn't usually top the charts quickly. Her singles perform how I'd like every song to perform. Increase in radio play means an increase in sales, which means longevity on the charts.
banners don't matter for the beginning. Britney and Gaga have made it to the top five without a banner but Beyonce hasn't made top twenty.
eh, I knew this song wouldn't perform well. It's not a good song.
I'm just saying. Don't expect too much from Beyonce on iTunes. She's usually a steady mover, and I don't feel the buzz is there yet. It's still growing.
