In their mega-hit "Cruise," Florida Georgia Line's Brian Kelley and Tyler Hubbard belt out

She was sippin' on southern and singin' Marshall Tucker
We were falling in love in the sweet heart of summer
She hopped right up into the cab of my truck and said
"Fire it up, lets go get this thing stuck."

Well, there's nothing "stuck" about this duo's career. It's red hot, in high gear and heading pell-mell for the horizon.

"Cruise" is the best-selling country digital song of all time, with sales surpassing 7 million, and it spent 24 weeks at No. 1 on Hot Country Songs - the longest reign in the history of the chart, which dates back to 1944.

Now Florida Georgia Line's new album, "Anything Goes," just captured the No. 1 slot on the Billboard 200 chart. "Anything Goes," released on Oct. 14, follows their breakthrough album "Here's To the Good Times," which was powered by the "Cruise's" meteoric success

Kelley and Hubbard just cruised through a Billboard magazine interview where they defended their style of country music, told how each of them discovered their love of music in church and admitted to smoking pot. The interview landed the no-holds-barred duo on the Billboard cover.

While discussing the rap by some that their music isn't traditional country in the Billboard cover story, Hubbard said: "In our generation, you can have a CD with six different genres of music on it. For us, it's all one thing, and if we have shocked people with our music, it's probably the older generation. Anybody that makes a mark or sets a new standard has a hard time at first, because people don't understand it."

"The definition of traditional changes every 10 years," added Kelley. "The Bakersfield Sound raised a lot of hell at first. Is Garth Brooks traditional? He wasn't [at first]."

In discussing how they both were given the love music in their separate churches, Kelley referenced their faith when he told Billboard, "The first time we ever wrote together, we were finishing each other's sentences. No record label, no one other than the man upstairs, can put something like that together."

When the Billboard writer spotted a small metal pipe on a counter in Hubbard's tour bus, which smelled like marijuana, he asked," Do you guys smoke?"

"Yeah. Oh, yes," declared Hubbard.

Maybe "Anything Goes" fits Florida Georgia Line better than most album titles fit most artists.
