I like hearing musical sounds. Upfront or not upfront.
For a surround mix to be a surround mix, it has to use the surround channels in a meaningful way. Whether that means floating instruments or ambience, it's up to the music for what it CALLS for.
This thread, like the quad thread, is there to highlight Atmos mixes that are called Atmos mixes, but do not utilize the non-stereo speakers in the way the music deserves.
For example, it's perfectly reasonable to expect a solo singer and a single guitarist to be upfront in an Atmos mix, and have the surround channels support with room ambience. In fact, if the guitarist was behind me, it would be distracting!
I like to think about it this way. The more elements a song has, the more justification to have instruments appear in surround channels, and even move around.
I think Atmos titles that don't utilize any of the extended soundfield should be given more importance in this thread rather than surround mixes that fail to use the height channels effectively but use the rears well. But that's just my opinion. One could very well make the case that an Atmos mix is not an Atmos mix without effective height channel utilization.
Anyway after a revisit of the Daft Punk Atmos mix it definitely does NOT belong in the Atmos Hall of shame (the other two titles I mentioned do), however, I do have OTHER gripes with the mix that frankly is a pure personal opinion and doesn't belong here.
