It depends on the music and instruments, for me it has to have lots of stuff going on, as much as I love AC/DC and Black sabbath it’s pointless having them in atmos when there’s more speakers than instruments
Atmos seems very suited to prog rock, electronic music and classical. I love heavy rock but can’t think of too many albums where i’ve thought “that would sound great in atmos”
Personally i’m more than happy with a good 5.1 mix as opposed to a crap atmos mix like Hootie and the blowfish
Exactly. That's pretty much my own approach to it.
I know some of you say that any kind of music can benefit from atmos (or 5.1, let's say multichannel in general) mixes, and you might have a point, but personally I wouldn't be interested in getting any music in surround that isn't layered or doesn't have any sort of production or sound design, especially if we're talking hard rock or metal with basic instrumentation. Honestly, I wouldn't see the point of getting something like Slayer, or a blues rock power trio without studio overdubs, in surround. However, I can see how some acoustic or "intimate" music, even with few instruments, can benefit from a surround approach if done tastefully.
As far as I'm concerned, my priotities with studio music are, in the following order:
1) I have to like it. I'm a listener who loves physical releases, but not a collector neither a completist, so I'm not buying anything I don't like.
2) Good mix and mastering (regardless of the format).
3) Ideally, the album will include a multichannel mix, but most of the times I don't need it to be interested in purchasing the album as long as 1) and 2) are there, although sometimes it will make the difference if I'm hesitant.
Additionally, I really appreciate having different mixes in the same release, as
@armyjazzer said. A Blu-ray disc that includes the original mix, a stereo remix, a 5.1 and an Atmos mix will be 10x more interesting to me than an Atmos release alone, especially if the 5.1 isn't just a watered down version of the atmos, but a different approach instead.
