At TUAW we've been following the DRM-free EMI track deal for some time. We're delighted to announce that these tracks will finally available for sale over at the iTunes Store later today (Apple announced they are available, but not in my copy of iTunes at the moment).
DRM-free tracks will cost you $1.29 each rather than the normal $0.99 per track you normally pay. The extra money buys you more audio quality than the standard DRM'ed tracks (256 kbps AAC versus 128 kbs AAC). Expect larger data downloads as your audio files expand to accommodate those extra bits.iTunes Plus requires iTunes 7.2.
