The Sansa slotRadio MP3 player from SanDisk that was first introduced at CES has been given an official release date on Friday, with the company announcing it will make the $100 player available then. Buyers will get a microSD card with the player preloaded with 1,000 popular songs from every common genre on the Billboard charts. While these files will be DRM-protected and only play on the Sansa slotRadio, users can plug in their own tracks on separate microSD cards.

Users can also buy albums on microSD cards from SanDisk's slotMusic selection, and an FM tuner is built into the small device, which is equipped with an OLED screen. [via Engadget]
