"Work from Home" seems like the perfect follow-up to "Worth It" for Fifth Harmony, and hopefully sets the pace for their career trajectory. The song is nothing if not run-of-the-mill, but still insanely catchy enough (which is the only necessary component for a vapid group like 5H, anyway) to work.
Not to mention they all look ~SMASH in the video and none of them seem to have webbed feet when it comes to dancing.
