YouTube TV ($72.99/month) includes NBC in virtually every US market. The unlimited DVR feature lets you record every episode of The Voice automatically and skip commercials. This is the closest experience to a traditional cable subscription.
If a GoMovies mirror asks you to "create a free account" to watch The Voice (many do to reduce pop-ups), you are handing over your email and password. These credentials are often sold on dark web forums. Never use a personal password on a pirate site.
Links break constantly. You may spend 10 minutes closing ads only to find the episode won’t load.
