Another famous rocker has found his way onto the list. This time it's Axl Rose, best known as the front man of Guns N' Roses. He is also currently the lead singer of AC/DC and is known internationally as one of the greatest singers of all time. We have Axl Rose to thank for hits such as Sweet Child O' Mine and Paradise city. Really, he's kind of the voice behind an entire era of rock.
Rose was notoriously difficult to tour with and often suffered from illnesses. It wasn't until 1990 that he spoke publicly about discovering homeopathic medicine and regression therapy. Rose claims he uncovered memories of his father sexually abusing him at the age of two. He blames this trauma for stunting his emotional growth and causing many of his health problems.
