Instead, the majority of songs will drop to 69 cents beginning in

The most popular songs will be less of a loss leader for the hardware. Relaxation of DRM suggests that Apple fears long-run competition from less regulated sources, including CD burning from friends. Most of all this is a sign that the music business continues to experience economic troubles. You could call it the "do anything to increase revenue now" strategy. For 30 cents a song you can make your entire current collection DRM-free.
