Lol, like 500k is some sort of accomplishment nowadays. You Xtina fans really know how to shade your own fave.
The song did not get a full treatment as a single. No music video and no push whatsoever from the label. It's surprising and definitely accomplishment that it outsold much hyped singles Not Myself Tonight and Your Body on its own, which just shows that it clicked with people (at least with the few people who were introduced to the song)
