• This Scooter Carusoe and Phil Vassar-penned song is the title cut of American Country Music Artist David Nail's second studio album. The track celebrates the power of music to create memories. Nail told Roughstock: "I used to make mix tapes and CDs and title them by the month or the name of the city I was going to visit. I still do it. Before a show, I make a playlist of songs I want to listen to and title it with the city we're playing. And this girl who used to drive me to school before I was 16 always had mixed tapes too. So when I heard this song, it reminded me of that, just driving and listening to Bob Seger, Merle Haggard, Elton John, Glen Campbell, Garth Brooks, and the Wallflowers - all on the same record. I eventually moved to Nashville and had all these aspirations: a million different times I pictured myself moving to Nashville or singing on the Grand Ole Opry. I feel like that's what this song says. These are the sounds of a million dreams."
• Nail explained why he chose this song to represent the album: "I've always felt that an album's title was the most important thing besides the music. It automatically gives someone an idea of what to expect," he said. "If you had to tell the story of me to this point, that song really sums it up."
• The song's music video was directed by Chris Hicky David and shot at the Alabama Theater in Birmingham, Alabama. Nail decided on the location after playing a Bama Rising Concert as a fundraiser to help tornado victims in the state.
  
  It is bookended by clips of Nail's family back home in Missouri, starting with old footage of the singer at the age of six, as his father introduces him on stage and ending with Nail's beloved grandfather telling him how proud he is. "It's songs like this that remind you of adolescence, being 15 or 16 years old and thinking, 'How do you do this? I really like singing, but coming from a small town like where I grew up, how do you start that journey?'" explained Nail. "If you didn't know anything about me, I wanted to visually tell that story in four and a half minutes, starting with me as a six year old, up to about six months ago, my grandfather getting his # 1 plaque for 'Let It Rain.' My grandfather is a huge Las Vegas fan; he and my grandmother drive out there three or four times a year. So the thought that his grandson plays Vegas and the thought that his grandson's name could potentially be on one of those marquees, just blew his mind."
• The song is a tribute to the classic cuts that Phil Vasser grew up with. "One day Scooter and I were doodling around and playing some music and somewhere the line, "sound of a million dreams" just came out," he recalled to The Boot. "We were talking about how these songs and artists we listen to on the radio had influenced us in our lives growing up. For me, they totally were and still are, the soundtrack of my life. 'The Sound of a Million Dreams' is really talking about that."
• Several lines in the song are straight out of Vasser's life, including the references to "Mainstreet" and "Mama Tried." "We were talking about 'Main Street,' the Bob Seger song, that's one of my favorite songs, and 'Mama Tried.'" Nail told The Boot. "Merle Haggard was my very first concert I saw ever. I saw Merle Haggard and Van Halen in the same week, so that kind of sums it up for me music-wise. [laughs] I always wanted to be Merle Haggard and David Lee Roth at the same time! I can listen to a song and I can still smell honeysuckle, or I can see these moments, being with a girl, all that stuff. These things take you back, and you forget about that."
