Tim McGraw created his own viral challenge called the #DeepCutsChallenge.
McGraw sang his favorite song "Take the Long Way Home" by John Schneider and then nominated Brad Paisley, Jason Aldean, and Kenny Chesney to sing one of their favorite "deep cuts" and post it to Instagram while tagging other artists to also participate.
Brad Paisley accepted the challenge and then nominated Darius Rucker, but made a strict rule that he couldn't do any Hootie and the Blowfish covers.
Rucker not only did the #DeepCutsChallenge, but then tagged Charles Kelley from Lady Antebellum to do the same.
Kelley came back with "Call Me a Dog" by Chris Cornell, and then challenged Russell Dickerson.
Russell actually sang a deep cut by Tim McGraw, paying homage to the man that started this madness, and tagged Thomas Rhett in to join the fun.
Rhett completed the challenge and then nominated Morgan Wallen.
Wallen fired back with a Jason Aldean deep cut before nominating Luke Combs.
Combs sang a Chris Stapleton track then tagged Vince Gill in.
