"I've never heard a Jay-Z song," she said in a video posted to her official site, MileyWorld.com.
Unlike past Miley hits, she explained, the track wasn't hers.
"I don't know, I didn't write the song – I picked that song because I needed something to go with my clothing line," she explained of her collaboration with Wal-Mart and designer Max Azaria, adding she didn't realize the track would take off. "It turned out for the best. It was really unexpected."
The young rocker said the pop track was a curveball from her usual style.
"I don't listen to pop music, that's not my style of music," Miley said of the track. "I'm really blessed for it to have done as well as it has."
While she may not be a Jay-Z buff, Miley also weighed in on an artist she has heard – dad Billy Ray Cyrus.
Asked if she would ever cover his hit "Achy Breaky Heart," she said no.
"That's like covering a Jay-Z song," she said.
