4. Pop fashion goes country
Grammy fashion was not ruled by a single color or designer, but rather a throw-back music-inspired aesthetic: the look of vintage country crooners. Bruno Mars and Macklemore rocked bolo ties, while Madonna and Pharrell wore ten gallon hats (Pharrell's oversized Smokey-the-Bear headgear unsurprisingly inspired many a Internet meme).
The hispter-fication of country-western style could even be seen in the performance of one of the genre's brightest stars, Kacey Musgraves. For her rendition of "Follow Your Arrow" she donned kitsch-y, light-up boots, a tacky prairie girl get-up and sang alongside some neon cactuses that wouldn't have looked out of place in an ironic Brooklyn bar.
5. When in doubt, play the piano
Nearly half of the live acts during the ceremony featured the headliners hitting some ivory keys, making the piano as prevalent this year as LL Cool J's use of the word hashtag was in 2013. Sure, the instrument provided some of the night's most memorable moments, from Taylor Swift's headbanging to Carole King and Sara Bareilles dueling pianos. But it's time artists realized they don't need a baby grand on stage to be taken seriously at the Grammys.
