The band wrote this song with Sam Hollander
, whose credits include "Acapella
" by Karmin and "High Hopes
" by Panic! at the Disco. "'Microphone' was so unbelievably sugary that at first I really wasn't into it, but Sam is really talented and it's an amazing song," American Authors bass player Dave Rublin told Songfacts
. "It's an interesting tune. I look at it as if it is galvanizing the people during these crazy times we are in. It's a message of extreme vivaciousness. Here we are with these blaring horns, calling on everybody to rise up. We're going to go out there. We're going to have a voice. There was such an energy that came along with the song, and sometimes that energy is what we fall in love with."
