Garth Brooks has seen a lot of stages and audiences throughout his career, and while out on his current World Tour, he's noticed that one thing in particular has changed a lot from his previous tours: The crowds are louder.

"I'm going to tell you, and you're going to think I'm crazy: It's something I call karaoke. It used to just be Dublin, Ireland, that could out-sing [me] -- you couldn't hear yourself singing when they were singing," Brooks told The Boot and other media before his concerts in Buffalo, N.Y. "Now, [it's] every city."

As on-stage technology has changed over the years, it's enabled Brooks to see his fans more up-close and personal, and he's says that he's seen some interesting things while looking out at the crowd.

"Our inhibitions to sing in front of people are being erased ... You see these people, and you swear to God, they think they're the only person in the entire room, so they're just -- they've got their head back, their arms are out ..." Brooks explains. "I can't tell you how many guys, 6 foot 6 or over, about 300 pounds, sing "She's in Love With the Boy" louder than any 16-year-old girl in the place.

"It's amazing, and it's so much fun to watch," he adds. "They've got an iPhone in one hand ... and a beer in another, and yet they're louder than they've ever been, so how is that possible?"

After spending so much time on the road, it might be easy to get tired of playing the same songs over and over again, but Brooks says that he hasn't become tired of singing a single one of his songs. His favorite song to play live? "Callin' Baton Rouge."

""Callin' Baton Rouge" is crazy fun, so much fun to play. But I'm very thankful ... there's no song that I'm tried of singing," Brooks says. "And people might go, 'What, you mean even "Friends [in Low Places]"?' "Friends" is fantastic. "Friends," I don't sing it. You play the first four notes, and it's gone, it's theirs.

"I mean, it's what I love, so you just keep watching and laughing," he continues. "It's pretty sweet. So things like "The Thunder [Rolls]," that's a big moment for us."

Another song that audiences have been taking to is one of Brooks' new singles, "People Loving People."

"It's been in some cities that caught me off guard for loving it -- Boston was a big one," Brooks says. "Boston was just one big love fest, and you know, anybody that knows Boston knows they're very quick, and they pride themselves on being very matter of fact, [but] these people just -- they were love bugs. They hate to hear that because they're so tough, but they loved it. It was great."
