A new digital music service is emerging from stealth mode, and looks like it it not only wants to take on Apple’s iTunes music service and iPod media player, but also take a stab at online music services like Pandora and go toe-to-toe with satellite-based music offerings like XM and Sirius.
Slacker, from Broadband Instruments, has launched a beta of its browser-based music service today, which (on registration) offers free ad-supported access to more than 10,000 Internet-accessible music stations; users can tune into a standard offering, or create custom station by entering their music preferences. But Slacker also plans to launch a PC-based jukebox application, a portable music player, and in-car satellite-based music receivers.
