Taylor Swift's new single "We Are Never Ever Getting Back Together" is selling much faster than initially thought. Industry sources now suggest the track -- released late on Monday, Aug. 13 -- will probably move easily move more than 500,000 downloads by the end of the tracking week on Sunday, Aug. 19. It even has a pretty decent shot of surpassing the 600,000 mark.

Yesterday, forecasters were suggesting it would launch with 400,000 to 500,000. But, once sources saw how well it was already selling, it blew all projections out of the water.

If it surpasses 448,000, it will earn the largest debut for a digital song by a woman in history. Lady Gaga's "Born This Way" holds the current feat among female acts, when it launched at No. 1 on Billboard's Digital Songs chart with 448,000 according to Nielsen SoundScan.

I'm literally crying tears of joy. My favorite little angel in the entire world is about to claim another record.

To be fair, "WANEGBT" has a full sales week, "Born this Way" only had 3 days.

I love the song by the way, it's a different sound but I can't stop listening to it.

I listened to it....so bland. I will never understand the appeal of this girl.

Sorry tender heart, these sales would be the highest in world history for a female.

Excuses excuses. This is Taylor's record.

Are you absolutely sure you're not 12?

Darling... Where in the world has anyone ever sold 600k+ in one week in digital sales? Nowhere... This makes it a world record.

Another article about this girl. She is not that good. Queensryche has 2 albums "Operation mindcrime" and "Empire". There lead singer Geoff Tate would kill Taylor Swift in a singing contest. Listen to that guy sing most underated singer. This girl is super produced pop candy and you suckers fall for it. She plucks a guitar and ppl thinks shes great. Band's create music and its alot harder. Stone temple pilots, alice in chains, metallica, Iron Maiden etc created great music. Everyone loves this pop crap now a days it blows my mind.

Excuse me? Taylor's vocal and writing ability excedes The Beatles, Pink Floyd, and even Ray Charles.... All combined. Taylor is a true artist and her lyrics will be involved in the world of music today. And BTW she isn't pop, she's a country singer.

Doesn't matter.
