I honestly didn't expect Dark Horse to do so well considering how many times she's announced it's not a single and how different it is from her usual material. Very proud of her. Honestly, Britney's team didn't think their plan through. Everyone knew Katy would be releasing over the summer and her eras tend to last long so it would drag into 4th quarter. Gaga was rumored for the end on 2013 and there's always the possible Rihanna album in November. Not to mention albums from Ariana Grande, Mariah Carey, and Miley Cyrus. Britney can't keep up with these artist and everything she does will be compared with them. She should've released early on in the year so she could shine and have her time. Now its overcrowded.
