SanDisk has announced that they are releasing SlotMusic, apparently in an effort to boost sagging CD sales. Teaming up with Sony BMG, Universal, Warner, and EMI, the company will be selling their microSDs to the record labels who will then create the 1GB cards. Each is only 0.6 x 0.4-inches and can hold 320kbps MP3, DRM-free music. Best Buy and Wally World plan on selling the cards, if they can find them in their stockrooms.
