The One Thing That Makes Carrie Underwood Sad on Tour

Carrie Underwood sometimes gets sad when having to choose which songs make it onto her setlist when she's out on tour.

When it comes to touring, Carrie Underwood will know what she likes and dislikes. The country music megastar has been all over the world while touring, with hundreds, if not thousands, of venues played during the time.

While Underwood's experience means that she has countless memories to draw from, she recently explained one issue that occurs every time she goes on tour.

"The hardest part of touring is figuring out what songs you're not going to do," Carrie told Taste Of Country.

Sounds silly, right?

Well, put yourself in Carrie's shoes. After all, each of her songs has a sentimental meaning, as they all represent different moments in her life. Deciding which of those songs will be sidelined can't be easy, especially when they all have a story to tell.

"Finding that perfect balance of just enough new stuff and obviously the ones that people expect to hear, but I always get sad, I'm like, 'Aww, we're not gonna do that one?'"

The funny part is that Carrie doesn't want to sing every song in her catalog. Well, at least not all in one night. Instead, she believes there's a shelf life for how long she's on stage. If she goes past that self-imposed time limit, she starts to give herself the ick.

"I can't be on stage for four hours singing my songs," Carrie said. "After two hours of my songs, I'm like, 'Eww,' and I'm hurtin'."

Carrie Underwood Also Does Surprise Shows, Too

Interestingly, Carrie likely goes through a similar ordeal when performing at one-off events. Perhaps that was an internal battle she had in December, when she made a shock appearance at her Nashville church's annual Christmas concert.

To be fair, Christmas events might be different. After all, the setlist practically writes itself. It likely helped that this past December wasn't the first time Carrie had decided to grace that specific stage with her presence.

Anyway, the point is that Carrie's body of work is so vast that it's impossible for all of her songs to make it into a setlist. As such, she's never going to be completely happy with her choices. Maybe that's why a Christmas performance is so liberating, because it takes all of the guesswork out of things.

That might be something someone wants to ask her in the near future.
