MusicMatch Jukebox has won numerous awards, including being voted the best personal jukebox by the editors of PC Magazine. MusicMatch announced yesterday that it is the first jukebox software with an integrated Internet Radio tuner. MusicMatch Jukebox is also the world's first personal jukebox software that lets users build extensive collections of CD-quality digital music downloaded from the Internet and recorded from music CDs, vinyl and cassette tapes. MusicMatch Jukebox gives users the ability to organize all of their tracks in a digital music database on their PC, create custom playlists and play them on their PC in CD-quality, and it's also the first jukebox software to offer personalized music recommendations to its users.

MusicMatch Jukebox is one of the world's most popular audio software programs, downloaded by over 1 million people each month. It is currently bundled with a number of hardware devices, including Creative Labs' NOMAD portable MP3 players and Sound Blaster Live! sound cards, and with select Dell(R) Dimension(R) and HP Pavilion PCs.

With Castanet, the efficiency of the information transfer to and from users will be optimized to enable MusicMatch to add new services to the core MusicMatch Jukebox platform. Customers will now be able to download music directly from the MusicMatch Web site, for example, and store it locally on their own PCs--without interrupting their other online activities. Castanet will help MusicMatch streamline delivery of detailed, personalized music recommendations to customers to help them enhance their music listening experiences. Castanet makes these services possible with an industry-proven Internet-based management infrastructure that includes built-in bandwidth efficiency, security and scalability to the millions.

&uot;MusicMatch Jukebox demonstrates a new era of digital audio. The fact that millions of consumers have already downloaded this Web-based personal jukebox application illustrates its impact on the new way in which consumers will locate and listen to music,&uot; said Jacqueline Ross, Vice President of Marketing at Marimba. &uot;We are delighted that MusicMatch has partnered with Marimba to integrate Castanet into MusicMatch Jukebox, and we look forward to MusicMatch's continued penetration of this rapidly expanding market.&uot;
