58 year old nurse Anne Muir was caught with 30 thousand copied files at her home in Ayr back in June 2008.
The raid followed a joint investigation with the British Recorded Music Industry (BPI) - the body which represents the UK record industry.
They removed computer equipment and found 7,493 digital music files and 24,243 karaoke files - worth an estimated £54,792 in the mainstream market.
The search also revealed that she was part of a ``sharing hub'', which meant users within her network could download music from her, Ayr Sheriff Court heard.
At an earlier hearing at Ayr Sheriff Court, Muir pleaded guilty to a contravention of the Copyright, Designs and Patents Act 1988.
Defence lawyer Lorenzo Alonzi said his client, an auxiliary nurse at Ayr Hospital, had not used the network for any financial gain, but to build up her self-esteem after suffering from depression for a number of years.
