Open channel3.gg in Chrome. Click the Install icon in the right side of the address bar:
Click Install when you get this prompt.
After installation, you can pin to the Windows taskbar alongside your other favorite apps.
Open channel3.gg in Safari. It has to be Safari.
Tap the Share button in the middle of the footer.
Tap Add to Home Screen.
Tap Add on the prompt.
BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.
Install the Channel 3 app from the Google Play Store.
Nintendo always has to go out and do things their own way, don't they?...
Funny enough, this app is really nice since we FINALLY have a way to officially listen to soundtracks from Nintendo games. The app doesn't have many games quite yet, but I'm sure more will come with time. They've already added 3 or 4 since launch!
There's a lot of neat features packed into this app, like using your Nintendo Switch play data to recommend music. The extension feature is nice, but it doesn't work for every song, and it's also not seamless for every song either. Whenever you extend a song, it'll most likely reset the playback back to 0:00.
The app also has some performance issues related to songs loading that rarely pop up, but it's a little frustrating when they do.
Nintendo Music might actually come close to taking over Spotify for me. Once Nintendo adds more music from their epic library of games, the value of it will skyrocket. The only thing that'd really make this perfect (and I know this will never happen) is if Nintendo made Music its own web-application or standalone download. I wish I didn't have to stream my Bluetooth audio from my phone to my Windows PC, but it is what it is.
