Garth Brooks' The Garth Channel on SiriusXM will sign off on Sept. 30 – six years after it debuted in September 2016.

The channel closing coincides with the end of Brooks' stadium tour, which recently ended in Ireland. Brooks always intended for the station to end with the tour as the goal of The Garth Channel was to support ticket sales for his stadium tour.

"My time with Sirius has been great," Brooks said. "It's all coming to the end of a chapter and start of a one. When this was all planned years ago, it was so everything would end out at the end of the stadium tour. So now the stadium tour has come to an end, and The Garth Channel will go with it."

Brooks said he asked Sirius executives if they'd be willing to work together again in the future and received a resounding yes.

"They've been very, very sweet," Brooks said. "So it's cool. We just have to see what's next for us, whatever that is."

The Garth Channel lived on channel 55 and played various genres of music curated by Brooks along with his favorite artists. The format changed over the years, with the station originally playing one of Brooks' songs every other song.

"Dude, that got old quick," he said. "And then like three songs, four songs, five songs -- you keep messing around and find the balance."

As for what's next for Brooks, he isn't sure about that yet. He thinks a tour of dive bars could be fun or a residency someplace. But he has something else in mind, too.

"Here's a spoil alert," he said. "How about being married to someone who has more Grammys than you do? Then you say, 'What is her future, and how do I be a mate to her and whatever she wants to do?' She's kind of in the same place in her life where she'll be starting new chapters. I want her to, without pause or hesitation to go, 'I want to do this.' Then my job is to be her love and her support."
