I think Tessanne Chin is going to suffer from being "too good" like what happens to someone every season. She'll survive a few rounds and then the voters will just get tired of her.
There should be a Voice drinking game:
Every time Adam says he's a fan.
Every time Adam says he has one complaint but it's an insignificant nitpick based on personal preference that means nothing.
Every time Christina has to sing a verse from the song just performed to draw all the attention to herself.
Every time Blake calls someone a superstar.
