A new study has highlighted that illegal filesharers tend to spend more on music in shops than those who do not regularly undertake the practice.
Commissioned by think-tank Demos, the poll found that broadband customers that have never downloaded tracks illegally tend to spend an average of £44 per person on music annually, while those who do spend £77.
One in ten adults were found to download music illegally, while eight out of ten were found to have bought CDs, vinyl and mp3s in the past 12 months.
The research could signal the potential danger of the government's plans to introduce new legislation that will force broadband providers to disconnect illegal filesharers.
Peter Bradwell, a researcher at Demos, said: "Politicians and music companies need to recognise that the nature of music consumption has changed and consumers are demanding lower prices and easier access to music."
Broadband providers such as TalkTalk have already criticised the government's plans.
