will be forgotten in matter of days

Cause Applause didn't use payola ?
And yet Roar sold more than Applause so your point is invalid

Receipts for the "Applause" payola? Gaga is not the one getting exposed here.

Also, if Capitol Records whole marketing scheme is about fabricating Katy Perry as a successful artist, who says they didn't strike a deal with iTunes too?

Her label probably purchased large quantities of her single to boost her image and it worked.

Until now.

The AUDACITY of a Gaga stan to come for Payola.

Honey, that's not payola. Look up the definition.

Payola is exchanging money for radio play, aka what KP just got exposed for doing.

Clear Channel often plays big new releases on top of every hour and that's not payola. It happens with all big 1st singles from major artists such as Madonna (GMAYL), Britney (HIAM), Gaga (Applause) and Katy (Roar).

What happens under the table with labels giving money for airplays is payola and that's what Katy Perry is doing here.
