it's not necessary though,she's just following the latest trend which is releasing the single->making the video->teasing it->and never releasing it just like Rihanna did with Pour It Up and Beyonce with Grown Woman, she even forgot to release the single
I will talk just when i'll see Dirty Laundry at #1 on urban radio...just to have a prove that her management presumed "strategy" has worked... because these updates aren't something unexpected , KDL had a lot of this big updates(at the beginning , in the middle and at the end of its run) but ended anyway mediocrely!
And the song is decreasing on urban airplay looks like her management "strategy" isn't working ad always
they waited to long to release the video. When it was having those amazing updates is when it should have been released.
But this song was way to personal to be a radio hit anyway. They need to dump the rest of the funds into Gone. To me it's her best shot at getting a hit single.
