Internet music sites are still going strong despite Napster's death and record industry law suits.
Analysts Nielsen/Netratings said that more than a quarter of the active online population - some 32 million people - visit such sites every day.
Free file-sharing application Kazaa drew more than 8.4 million unique visitors for one month, representing a 148 per cent growth since the beginning of the year.
Industry-backed subscription services have also done well. The Sony and Vivendi joint venture Pressplay.com posted 640,000 unique visitors in August, surpassing its total for the first three months of 2002.
Netratings analyst Carolyn Clark said the survey showed that subscription music sites are slowly "gaining more traction".
But she warned that much work remainsed to convince the mass audience that curently downloads music to convert to paying subscribers.
