Luke Bryan's newest No. 1 hit "Knockin' Boots" has fans dancing in the aisles, even if they don't want to.

The singer says what he finds most intriguing about "Knockin' Boots" is how catchy it is.

"I’ve had fans go, 'You know, I really don’t like that song but I can’t stop singing it,'" Bryan tells Taste of Country. "I look in the aisles and husbands and wives are out there twirling and dancing. It's kind of a nice little fun dance song, too."

It's arguably the song of the summer, although Bryan concedes that Blake Shelton's "God's Country" could give him a run for that title. "Knockin' Boots" is the first single from Bryan's upcoming seventh studio album, which is still very much TBD. In fact, even he's not sure when fans will get his next album.

"I think it's a fun time in music. Even with 'Knockin' Boots,' we were like — we didn't really have a song picked," the longtime hitmaker says. "I went in and recorded a couple songs and we were like, 'We like it, it's summertime, let's put it out.' I think the freedom of kind of put a song out when you want to is pretty nice."

The 43-year-old talked to Taste of Country before his set at Hometown Rising in Louisville, Ky,. on Sept. 15. During the interview (seen above) he also gave fans a little insight into what his next album may include.

"I'm not gonna have some album with every track is gonna have steel guitar on it, but do I have steel guitar on this album? Yeah," he says.
