Nowhere did I say it'd be limited to DRM, I said it would be limited to music purchased from the iTunes store. Even though today's iTunes music doesn't contain DRM it is still fingerprinted and Apple (and iTunes) know exactly whether a song in your library came from the store or whether it was one you ripped yourself. I'm pretty sure only the former will appear magically in your cloudstore without an upload, and I suspect the latter will never be welcome.
