Every week our sister blog, Read/WriteWeb, has a feature called Read/WriteWeb Files, in which they investigate a current hot topic or company in Web technology. This week they’re going to focus on Online Music, something that is becoming more and more prevelant as broadband speeds increase and social software functionality gets better. Here at last100, we’ll also be contributing to the Read/WriteWeb Files, with a series of posts on digital music services, devices and the state of the music industry. Our other sister blog, AltSearchEngines, will also be publishing a list of their Top 10 music search engines.
