This is How You Stop an Artist in Their Tracks

Never sign with a label, and never put your career in the hands of a producer:
A petition has been launched to release Kesha from her record contract.
Over 53,000 people have signed the Care2 petition demanding Sony Music Entertainment release the pop star from her record deal.
Kesha has been locked in a legal battle that has allegedly prevented her from releasing new music since 2013.

The singer filed a lawsuit against Dr Luke for "mental manipulation, emotional abuse and sexual assault" last October. She is looking to be freed from her contract with the producer.
The legal system has to change. No one should be able to lock up an artist and keep them from working. It's completely unfair and it shouldn't be legal to use a contract in this manner. I would think that a percentage payment would be due to the producer in this case if Kesha were to release music on her own and make money, otherwise no one would sign a contract ever again. But to tie her hands and deny her the ability to make a living is wrong.
