Miley Cyrus
Miley Cyrus is another product of the Disney Channel who has been able to outgrow that era into a successful singing and acting career. There is no denying she is a serious performer, but many have said that her singing ability is just not that impressive.
Bono
Of course, there was a time when U2 was on top of the world and seemed completely untouchable. Those days have passed, and Bono’s more recent singing abilities have seemed to decline. He can no longer hit the high notes of older hit songs while singing live, but he is still a legend.
