Leading up to Hillary Clinton's acceptance of the official Presidential nomination for the Democratic Party on Thursday, she was cheered on by many musical friends and fans, who lent their talents to supporting the first female nominee from a major political party.
From Katy Perry's powerful Olympic anthem to Elizabeth Banks' star-studded a cappella cover, here's a look at the best musical moments from the 2016 Democratic National Convention.
1. KATY PERRY
Perry, who has been stumping for Clinton since before the primaries, took the stage on the final night of the convention to address the crowd prior to her performance, urging viewers and fans to register and vote.
"On Nov. 8, you'll be just as powerful as any NRA lobbyist. You'll have as much say as any billionaire," she told the crowd. "Or you can just cancel out your weird cousin's vote if you'd like."
Perry, who had boyfriend Orlando Bloom supporting her from the convention crowd and was snapped holding her hand backstage, then performed her Olympic anthem "Rise," before launching into her powerful ballad "Roar."
2. HILLARY'S HAMILTON SHOUT-OUT
While accepting her nomination as the first female presidential candidate from a major party, Clinton couldn't help but shout out 2016's other dominant political headline: the hit Broadway musical, Hamilton.
"Thought we may not live to see the glory -- as the song from the musical Hamilton goes -- let us gladly join the fight," she told the crowd. "Let our legacy be about planting seeds in a garden you never get to see."
Hamilton creator and star Lin-Manuel Miranda was predictably thrilled with the shout out, sharing on Twitter, "I'm with her. #AndShesBeenListeningToDiscTwo!"

Following her remarks, the 23-year-old delivered a powerhouse performance of her hit single, "Confident." (Lovato's performance begins at 02:05.)
4. ALICIA KEYS
Keys used her platform on Tuesday to address the issue of gun violence. Before launching into a performance of "Superwoman," Keys told the crowd: "I dedicate this song to the mothers of the movement and all mothers who have lost their sons and their daughters to senseless violence. Until we deal with gun violence in this country, we can't claim home of the brave."
Later, she rallied for unity within the Democratic party. "Tonight is a celebration because we are stronger together," she declared. "Let's acknowledge our differences and celebrate them. Dr. King said, 'The last word must always be love!'"
5. ANDRA DAY
Day kept her focus on the performance, showcasing her absolutely stunning vocals on "Rise Up" without additional commentary.

8. LENNY KRAVITZ
