For instance, "California Gurls" (featuring Snoop Dogg), the lead single from Teenage Dream, also entered the Hot 100 at No. 2 (May 29, 2010). It dipped to No. 3 and then rebounded to No. 2 before spending six weeks at No. 1. Similar to how "Roar" trails an established smash in "Lines," "Gurls" waited out Usher's "OMG" (featuring will.i.am), which topped the Hot 100 in each of the first three chart weeks for "Gurls" before the latter took over at the top.
Blurred Lines I'm here for it getting a another record of 17 weeks atop the Hot 100
If any song deserves it, surely Mr. Thicke does still not sick of it
How come TiK ToKs opening week was that big? It was her debut single, where did the momentum come from (it could not be Right Round, come on now )
Because it wasn't its opening week. That's why "Roar" becomes the 3rd highest digital sales debut behind "We Are Never Ever Getting Back Together" and "Right Round".. Ke$ha's classic historic sales were on Christmas
WANEGOD it's impact
