While Skype has become a widely used program, many have abandoned Kazaa in the past few years due to it's inability to illegally download music safely and correctly (for example: trying to download Yoshimi Battles The Pink Robot and ending up with pornography that probably isn't legal in the United States).
In order to jump on the streaming music bandwagon, for the low price of $5-$10 a month, consumers will have easy access to an enormous 5 million song library from their PCs or smartphones with the new program Rdio. About to be launched as preview software in the U.S. before it becomes available to the public by the end of the year, Rdio reportedly has the four major labels and assorted indie labels on board with their plan. It makes sense, labels are pretty much on board with anything these days that says "new technology" and "paid subscription."
The program also takes a tip from Pandora, giving the user the ability to discover new music through listening patterns and favorite artists. It also apparently can sync a user's iTunes library with Rdio, allowing users to keep all of their music in one easy place. And, from the screenshots, it looks a lot like something you already are familiar with, Last FM.
Will it work? If everyone in the world stopped both torrenting and downloading via Rapidshare, yeah, it might have a shot.
