Sure, their songs help us through both a workout or a heartbreak, but that's not the only reason why we love some of the biggest names in music today: with their OTT fashion choices (hi, Katy!) and headline-making antics (don't stop, Miley), we can't take our eyes off of these musicians—or their enviable Instagram accounts. And of course, we're excited to see what they have in store for us at the 2014 Grammy Awards on Sunday night. Catch up with our favourite cover girls (from Taylor Swift to Pink) and track the fierce sartorial journey that's Beyoncé's epic style evolution before they hit the red carpet. Now.
