The act updated laws to expand copyrights for musical engineers and producers and also created a method for compensating for artists when digital services use their work.

It was a star-studded affair, beginning with Maroon 5 keyboardist P.J. Morton performing the national anthem. Morton also presented Adams with the Creators Leadership Award, calling her his “Auntie Yo-Yo.”

The 4-foot-11-inch Chenoweth joked that the impressive award "weighs more than I do.” And she took a moment to share her admiration for Pelosi.

“I love you so much," she told the Speaker. "I was there for all of [your] recognitions, and I always will be.”

Chenoweth sang “For Good,” a hit from the musical “Wicked,” alongside Duke Ellington High School student Kesaundra Haythe. The two had not rehearsed before but delivered a captivating performance, receiving a standing ovation.

Kat Graham, who starred in "The Vampire Diaries," and Mario, a two-time Grammy nominee, presented Jeffries with his award and lauded him for his “lifelong commitment to hip-hop.”

While Grassley could not attend, Neil Portnow, who is retiring as CEO of the Recording Academy in July, presented an honorary Grammy to the senator earlier in the day.

Also at the event were producer Ian Fitchuk who worked on Kacey Musgraves's "Golden Hour," the Grammy album of the year; 15-time Grammy-winning record producer Steven Epstein; Talking Heads keyboardist Jerry Harrison; and D.C. native and Grammy-nominated singer Kenny Lattimore.

On Wednesday, the Grammy winners and nominees will head to Capitol Hill to meet with lawmakers and staff to discuss ways to protect artists' rights in the face of new online streaming services.

Adams told ITK that she expects the talks to be productive and important for music advocacy.

“I have found that people are not against [music advocacy]. They’re just people who you need to educate on the importance of music because we all know that music signifies different parts of our lives," she said.
