Since a relaunch late last year, music service Exfm has reportedly grown to 300,000 active users (up from 75,000). The company also has raised $1.5 million in new funding.
Previous to the relaunch, Exfm was a web browser extension. Now its a "full fledged web service," writes Venture Beat. The service offers various "channels," each filled with music gleaned from blogs. Like the Hype Bot, Shuffer.fm and other service, Exfm turns music blogs into an almost radio-like experience.
