A Cheltenham hairdresser has been told she could go to prison if she plays CDs or tapes to her customers again.
Ms Morrison can expect to pay legal costs
Heather Morrison, who owns Zak's Salon in the High Street, was sued by the licensing body for the music industry.
The High Court heard that an inspector from Phonographic Performance Ltd (PPL) found her playing CDs without a permit.
Ms Morrison said she stopped as soon as she was told she was breaking the law and was "gobsmacked" by PPL's legal action "targeting a little company".
She said that after the inspector called two years ago, she took her CD collection home and played the radio instead - which she is allowed to do without a licence.
But she admitted that she did not attempt to get a permit after the visit.
Ms Morrison did not attend the court hearing on Thursday, but has been told she faces a £10,000 fine and up to two years in prison if she fails to obey the order.
She can also expect to pay more than £1,000 in legal costs.
After the hearing, she said: "I'm angry and upset about it as well as being gobsmacked.
"I can't believe a big firm wants to target a little company. It's like Big Brother investigating small fry."
