I'm going to go out on a limb and state that the number of unreported or unprosecuted rapes far, far outweighs the number of false accusations. Being indicted (not merely arrested) for a crime should always remain a part of public record.
Devolution is correct: a large portion of hip hop music in general is disrespectful to women and objectifies them as sex objects. It also promotes a definition of masculinity defined by sexual prowess/promiscuity, and opulent spending.
But I truly believe that the music is reflective of the rape culture pervasive in America, not responsible for it. I'd really love to have someone sit down and interview these guys after the trial (make no mistake, they're all going to jail for a very long time) and ask them
why they did it and how they felt about it. I think you'd find a widely varying mix of remorse, peer pressure, sexual excitement, and utter contempt for the victim amongst the group.
From the South African study on gang rapes:

"Rape is an expression of male sexual entitlement," said Rachel Jewkes, chief researcher for the survey conducted by the government-funded Medical Research Foundation. "South Africa is an immensely patriarchal society. The history of the country has shaped the dominant forms of South Africa's racially defined masculinities."
For Rebombo, rape was a means to prove his manhood.
As a teen, he said he was cruelly taunted because he was not circumcised. Circumcision is considered a rite of passage in some tribes but his father had almost died as a result of the unsanitary and brutal procedure, and swore his son would not be abused that way.
So Rebombo was subjected to daily, constant jeering.
"I was viewed as not man enough," said the large, soft-spoken man.
Peer pressure involving girls
Other boys pressured Rebombo to "teach a lesson" to one teenage girl who did not want to go out with them. He resisted at first, fearful of his religious parents and their good standing in the community. Then he relented.
On that Saturday, Rebombo was plied with beer and marijuana to overcome his nerves. "I had difficulty breathing," he said. "I had never had sex before. I was terrified."
The girl was brought to a field and Rebombo and another boy were left with her, he said.
The other boy "started raping her. She fought him. I was just there, dizzy with all the stuff. He just stood up and said: 'Your turn.' I was there on top of her," he said.
Afterward, "she just ran home."
It's passed down from generation to generation. The older guys in this case were probably similarly sexually initiated when they were younger. Though traumatic, rather than rejecting those that pushed them into it, they normalize their behavior by repeating it to another generation of teens when they get older. This cycle allows them to reconcile the actions in their minds because "hey, everybody does it."
