One of the main lines in the song is "Who's got it better than us? Nobody. Who's got it better than us? Nobody."
Bay Area rapper Bailey created his tribute to the team by sampling some of coach Jim Harbaugh's locker room rants. The team heard it, and loved it.
"I talked to them about it. They say they play it at practice. I told him I was Bailey, I got the song. They said 'We love it. We love it. You keep on going.' I said, 'You keep on going,'' said Bailey.
The 49ers chant is also featured on a new Mission District mural. The game against the New Orleans Saints is Saturday at 1:30 p.m.
