Earlier this year, the last of the four major music labels offered its respective catalog for digital download to Amazon.com's music service in the MP3 format with no digital copy protections, giving users the ability to freely transfer songs to any portable MP3 music player.

With all of the Big Four record labels now jettisoning digital rights management, music fans have every reason to rejoice. But consumer advocates are singing a note of caution, as the music industry experiments with digital-watermarking technology as a DRM substitute.

DRM-free music sells at a much higher rate online than protected music, according to UK-based digital music store 7 Digital. In fact, customers buy it four times as often as they do DRMed music. As a result, almost 80 percent of the store's sales are of DRM-free content.

At this week's Digital Music Forum, lawyers managing digital rights for Microsoft's Zune music download site and RealNetworks' Rhapsody said that they too believe digital rights management to be more of a headache than an asset.

Music education is a field of study connected with the learning and teaching of music. Music is an essential part of the fabric of our society, and the intrinsic value of music is widely recognized. Human culture uses music to carry forward its ideas and ideals.

Despite the recent announcement of "DRM-free" music tracks by Apple and Amazon.com, Digital Rights Management (DRM) is not about to go away. At least, that's the main conclusion of a report, "Digital Rights Management Update," made available this week by the market research firm In-Stat.

The Dejunair Project creates "Free and Open Source Music" or "Open Music". This means simply, you can use the music for whatever you want at no cost (free beer!). You can use the tracks for podsafe music in your podcast, backing or overlay music in videos, remix for a total new track, or whatever else you can dream up.

Now this is interesting: with the arrival of a demand for some $4.5 million in damages, one of the founders of Pirate Bay has come up with an innovate method of paying it and attacking the music industry at the same time.

I've wanted to write this article for quite a while. Over the years I've noted that Java-based music and sound applications have increased in number and quality, yet no comprehensive list or summaries have covered these advances. And so at long last I present this survey of music and sound applications that require Java.
