I don't know about the others but for music on the Note 7, I had to download Samsung music from the app store. Only Google play music was preinstalled.
So did you just ignore everything else I wrote and pick out one thing that wasn't on your Note 7 ?? Even disregarding that; it's still dependant on either carrier / region firmware.
But the point remains. Samsung's duplication of Apps and services that come pre-installed on it's devices is entirely different to your proclamation that Apple has duplicated services and apps, which as i pointed out, those alternatives which DO NOT come pre-installed are therefore NOT duplicates.
When you factor in with Samsung, other ancillary Apps like Facebook, Instagram, Messenger, Twitter, Skype and such which may come pre-installed (again dependent on firmware variation) and it's no wonder Samsung receives the criticism it does for pre-installing a lot of needless bloat.
The S8 as great as the hardware will be; will undoubtedly follow Samsung's pattern and we will hear rumours of a less heavy TW prior to release, and then discover on release it still comes with anywhere between 48-56 apps pre-installed and at least a dozen of them are apps with duplicated functionality of Apps pre-installed on the device.
Adding yet another app to that list, even if it's a step beyond S-Voice is not something I am going to get excited about.
