• This upbeat cut was released as Rascal Flatts' fourth single from Rewind. The song was penned by Dan + Shay's Shay Mooney, songwriter Jesse Frasure (Florida Georgia Line's "Sun Daze") and pop queen Meghan Trainor. "'I Like the Sound of That' is one of the most fun tracks that I had the opportunity to work on for this record," says Flatts' member Jay DeMarcus. "The melody is so infectious, the lyrics are fresh and we're absolutely thrilled that it's our new single."
• Surprised to see Meghan Trainor as a co-writer on this song? Before Trainor found fame as a pop star with her chart-topping hit "All About That Bass," the songstress was a songwriter-for-hire who earned herself a good reputation for being able to write in a number of genre styles. Her other early songwriting credits included tunes co-penned for country star Hunter Hayes, Disney starlet Sabrina Carpenter and Hot Chelle Rae singer Ryan Follesé, as well as co-writing another track for Rascal Flatts - "DJ Tonight."
• Shay Mooney and Jesse Frasure arrived first at Major Bob Music on Nashville's 17th Avenue for their songwriting session. Mooney came up with an upbeat guitar groove, while Frasure started building a track on his laptop. When Meghan Trainor turned up with her ukulele, Mooney flicked through his log of song titles on his phone and suggested. "I Like the Sound of That" as one that fitted the mood. "I wrote it down because it's something I say all the time," he recalled to Billboard magazine. "I always would say, 'Hey, man, I like the sound of that.'"
  
  The trio then started working on the lyrics, focusing on the household sounds that one associates with a romantic partner, beginning with the splatter of a shower. "It's just the kind of noises that go down when you're not alone in the house, those routines that you get used to but would kind of miss if they were gone," Frasure noted. "I think it was the shower scene that really opened up the whole thing."
• The music video cuts between footage of the band recording the cut and performing it live. "This song has become one of our favorites to play live. So with this video, we wanted to show a bit of the process of taking a song from the studio to the stage," Jay DeMarcus said. "We always end up having a lot of fun together in the studio, and I think it lends itself perfectly to the good-natured vibe of the track."
• When the Rascal Flatts trio first heard the tune, they were surprised that neither Meghan Trainor or Dan + Shay wanted to record the song themselves. "I actually called Jason Owen, Dan + Shay's manager, and said, 'Why aren't they cutting this song? It doesn't make any sense to me. This is a smash,'" Jay DeMarcus recalled at a media event. "But he was kind enough to give it to us."
• DeMarcus liked the song's sound from the very first listen. "I love the chorus. I thought the chorus was extremely, extremely hooky," he noted. "We did change [it a little]: We sped it up a little bit from the demo, and the bazooka hook in the beginning is ours; we came up with that. We tweaked a few lyrics here and there. But the chorus just stayed in your skull."
• Rascal Flatts guitarist Joe Don Rooney said that the song's lyrics are relatable no matter how old you are. "It talks about all of the stuff that the younger generation talks about in a hip way, but yet all generations get and understand," he said. "I think it's very universal, I think it's very hip and cool, and that's exactly what we look for in a country song."
