It themes a ton of apps like Whatsapp, Youtube, Viber, Instagram, Gmail, etc. It's probably the most comprehensive CM13 theme on the playstore.
I think it's very well designed, with a well defined design guide and careful attention to spacing and uniformity. I've found that a lot of the free themes (and even some pro ones) are nothing but random splashes of color with no sense of direction.
The developer is always updating it once or twice a week, adding support for new apps and improving the existing ones. You can also contact him to add support for a specific app.
Really worth the toonie or so I paid for it a while ago!
I had better luck with CMTE than Layers, personally. Maybe it's just because I found a CMTE theme I really love (Swift Dark, no affiliation with the creator of it, I just think it looks so polished and awesome), and found nothing of comparable quality on Layers.
I'm currently using the only dark theme that I've ever thought was good. Swift Dark. It's for the CM theme engine and it actually looks like an official Material Dark theme. It's really polished.
Awesome, and just to confirm, I could unlock bootloader and get TWRP installed, then update to 7.1.1, and then finally install SuperSU to root?
Personally I'm not a huge fan of Atmos myself as audio seems almost muddy through my headphones. Atmos is definitely amazing with the phone speakers though.
As for customization I'm probably SOL then, Nova is what I currently use but doesn't support themes. This is what I'm looking to use. I had purchased it previously and used it on multiple devices and I really, really miss the blacked out GMusic and Gmail lol.
Edit: Woo! Just found out that if I'm rooted I can install Substratum and get themes for that which would eliminate the need to go custom ROM!
I just use Dark wallpaper and a theme that puts popular apps in completely dark mode (https://play.google.com/store/apps/details?id=com.brit.swiftdark&hl=fr).
The invert color is horrible in my opinion.
Can you suggest a layers "theme" which would be as complete as say Swift Dark CMTE theme? I'm talking complete system UI and all google apps (especially hangouts).

https://play.google.com/store/apps/details?id=com.brit.swiftdark Swift dark is the best. It comes with an AMOLED black theme included. My favorite and only theme.
Swift Dark, beautiful theme, amazing developer who continuously tweaks and updates https://play.google.com/store/apps/details?id=com.brit.swiftdark
If have a ROM with CM theme engine installed, Swift Dark has a dark Allo theme.
Swift Dark, regularly updated and a lot of other apps themed dark -> https://play.google.com/store/apps/details?id=com.brit.swiftdark&hl=en
Swift Dark is one of the most polished and complete dark themes I've found: https://play.google.com/store/apps/details?id=com.brit.swiftdark
If you prefer light themes with colour, Pop UI is excellent: https://play.google.com/store/apps/details?id=com.monish1995.theme.popui (there's also a dark version)
Edit: Forgot one - Flux: https://play.google.com/store/apps/details?id=com.flux.theme.flux
Mine looks extremely similar to that, I use Swift Dark CM12/13 theme, it themes the whole system and most of the app.

If you're rooted, some CM Theme Engine themes do it. This is my favorite theme. They have a screenshot of Play Music in there.
I don't think there is currently a module for that at the moment.
I think you're better of using a dark theme for one of the theme engines (CM themes or layers)
I've been using the swift dark theme to achieve the look I think you're looking for. It's not free but I'm sure there are free alternatives.
