Keith Urban is used to being on top. The singer has notched 20 No. 1 hits on the Billboard charts since the year 2000, and the country superstar -- an Aussie who moved to the United States with little more than a guitar and a dream -- admits that his string of success is almost beyond his comprehension.

"It feels amazing," Urban recently told The Boot and other reporters. "It’s so weird. I don’t feel like I’ve ever had specific, detailed goals; they were just broad-stroke wants and hopes, really -- broad-stroke hopes that I could get in and record a song and get it on the radio, and then hopefully be able to put a band together and tour. That’s pretty much the broad-stroke hope, and do it here, on the biggest country stage in the world.

"The first time I got to hear myself on the radio here was mind-blowing," he adds. "It still feels surreal, after this many years, getting to hear my music on the radio. The fact that it’s happened 20 times is, I never imagined that would happen, nor could it."

Since his first single, Urban has landed songs on the charts every year -- an impressive, and rare, feat in country music. While Urban undoubtedly works just as hard as other artists, he credits his success to his tenacity and ability to reinvent himself time and time again, especially with Ripcord.

"I never felt like I had a dry spell," Urban maintains. "I think I found new gears that created more liberation for me, creatively, as a writer and also as a performer, to make the kind of records I wanted to try and make. Getting in the studio and getting a little bit of that feeling, which I did with Fuse, was the first time where I had sort of broken out from my usual way of making records. [I] reached out to [producer] Ross [Copperman], and was just working a lot with people I was writing with as well, which is what we did on that record. It felt very liberating, so I think I’ve just continued on that particular path.

"I feel that has almost made it feel like everything is new again," he continues. "The way I go about making records feels very, very new. In some ways, this feels like my second album."

Ripcord is available for download on iTunes.
