I hate Pentatonix, because they run middle of the road, or both sides, so to speak.
Middle of the road(borderline) is the method used to pull christians away from their conservative beliefs.
In the extremes, you'll find one extreme that's totally evil, & the other totally good & righteousness.
Pentatonix has a very good sound, but then again, it's not the sound, but the content that matters, as well as the purpose behind it.
For example, what if the Mormon tabernacle choir sang your favorite worship chorus? You know it would sound good, yet all the singers are sinners.
It's kinda like eating a steak dinner on a used garbage can lid.
