Napster will launch its first mobile-download service for Europe in Ireland later this month on the O2 Ireland network.
Customers will have access to Napster Mobile's catalogue of three million songs, ringtones and artist images.
The service will be available initially to O2 Ireland customers with handsets using NTT DoCoMo's iMode mobile-internet service. By January, WAP (Wireless Application Protocol) and Java-enabled handsets will also be able to use the service.
By February, songs purchased on Napster Mobile can be sent to a user's PC as well as their handset, the companies said. Napster does not currently have a PC download service in Ireland.
The Napster Mobile application will be shipped with some iMode handsets by O2. The application includes features such as a recommendation engine, which can pick other songs a user may like based on their past picks, plus abilities to search, browse and preview content.
Last month, Napster agreed with TMN Portugal to launch Napster Mobile for its five million subscribers, but no timetable was given for the launch. Other European countries are expected to follow.
