I only vaguely knew her name, never really followed her career. But my wife has some of her songs on a country playlist she plays occasionally, and the song “Wheel of the World” really caught my attention. Total earworm. I was curious as to whether it had been a big hit, so I turned to Wikipedia.
Per Wiki, the album it came from, Carnival Ride, debuted at #1 not just on the Country chart, but the overall Top 200, “achieving one of the biggest ever first-week sales by a female artist” and ultimately going quadruple platinum. Five singles were released from the album, four of which went to #1 on the Country singles chart, and all five made the top 30 of the Billboard Hot 100 (which includes all genres of music). But (as you can obviously guess from the title of this thread) “Wheel of the World” was not one of them! 
I just don’t understand how you have an album that is cranking out hit after hit, but then after five hits you leave this track on the bench. “Nah, we’re good. Time to close up shop.” What? :smack:
I listened to the other five, and the only theory I can come up with is that maybe it wasn’t “country enough”? But since when are record labels allergic to crossover hits? I don’t get it.
