Katy Perry – “Birthday (Holy Ghost! Remix)”

It’s Friday, and it’s summer, and the World Cup is in full swing. It might as well be all of our birthdays, and we might as well celebrate with Holy Ghost!’s smooth and scintilating remix of Katy Perry’s latest hit. No idea if this is officially sanctioned, but it’s officially got me spinning in my desk chair right now. Swerve into your weekend below.
