Class Select Theme (MvM Version) - Team Fortress 2

"Class Select Theme (MvM Version) - Team Fortress 2" is a high quality rip of the MvM Version of "Class Select Theme" from Team Fortress 2.

Joke
At 0:08, the music slows down a bit and the melody is changed to the The Nutshack theme, complete with the Heavy's voice sentence mixed into “It's the Nutshack” playing whenever it would in the original theme. The actual Nutshack theme is also mashed up in the background. In-game sound effects, mostly from Mann vs. Machine, including robot voice lines, take the place of the chatter and the rest of the lyrics from the original theme.
