The sixth edition of #musicMLK brought new energy and excitement to the effort to infuse one of America's greatest holidays with music, service, and artistic expression. Partnerships with Google/YouTube, Smule, and the Corporation for National and Community Service helped provide a signal boost to inspire more musicians and music-lovers than ever to organize music actions from coast-to-coast, including Puerto Rico. Thank you to everyone who picked up an instrument, sang a song, brought a smile to someone's face, or chimed in with a tweet. Onward!

Below, we've curated some of our favorite shared media.
