After tinkering with the idea and teasing many, EMI has decided not to pull DRM from music they make available. While initially seen as the most likely group to push for DRM-free music, they have broken off talks and pushed back what many were hoping for. It's not a particularly surprising, given the current nature of the market. The most successful digital download store, ITMS, is DRM-laden, and likely unless they pushed for it, odds are it wouldn't happen.
Money was likely a factor here, with EMI asking for very large upfront costs from download services to cover (potential) costs.
