"One Step at a Time" will mellow out just under 20 for this week and half of next, but will burst through and climb to the 10 as airplay continues to grow.
"Better In Time" will climb and hover outside top 30 then crack through, and like "One Step at a Time" will increase fast as airplay increases.
"Just Dance" will go top 30 after SYTYCD performance.
"7 Things" will go #1 this week because of the whole album release thing. "These Four Walls", "Full Circle", and "Breakout" will go top 100.
"Duisturbia" will go top 4 after video is released.
^I know the post wasn't to me, but I'd actually say that the song is moving at the perfect speed I mean, I'd rather downloads be higher when airplay is higher, rather than dowloads peak before airplay does. I mean, the song hasn't even debuted on the Hot 100 Airplay yet, it probably will next week though, so I'd say downloads are fine.
