[Chorus: Mick Jagger & will.i.am]
You can go hard
Or you can go home
You can go hard
Or you can go home
You can go hard (You can go ha-a-ard)
Or you can go home (Or you can go ho-o-ome)
You can go hard (You can go ha-a-ard)
You can go home
Ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-check it out

[Verse 1: will.i.am]
My mama told me "Willie rock harder"
Don’t be no dummy, be a lil’ smarter
Don’t be like your daddy, finish what you started
Aha momma, imma rock hard, check it out
Fly high Willie, I been a charter
I won’t forget my place, call me rock harder
You know I kill it, kill it baby, leave the slaughter
I'll be gettin' dollas', mama, I’m a big baller, check it out
I’m hip-hop hard, rock a boulevard
Willie’s in charge, I don’t need nobody now
I go on and on, on and on
On and on and on on on on on on on on

[Chorus: Mick Jagger & will.i.am]
You can go hard
Or you can go home
You can go hard
Or you can go home
You can go hard (You can go ha-a-ard)
Or you can go home (Or you can go ho-o-ome)
You can go hard (You can go ha-a-ard)
You can go home
Ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-check it out

[Verse 2: Mick Jagger]
Hard like a rock 'n roll
Time bomb's ticking, explode
Baby, this is dynamo
Better move back now, it's 'bout to blow
Hard like geometry, and trigonometry
This is crazy, psychology
Get it, baby, I'm 'bout to win
Watch out now, I'm going in (Going in, going in, going in, going in, going in, going in, going in, going in)

[Bridge]
Ooh-ooh-ooh-oooh, ooh-ooh-ooh-oooh
Ooh-ooh-ooh-oooh, ooh-ooh-ooh-oooh

[Chorus: Mick Jagger & will.i.am]
You can go hard (You can go ha-a-ard)
Or you can go home (Or you can go ho-o-ome)
You can go hard (You can go ha-a-ard)
Or you can go home (Or you can go ho-o-ome)
You can go hard (You can go ha-a-ard)
Or you can go home (Or you can go ho-o-ome)
You can go hard (You can go ha-a-ard)
You can go home (Or you can go ho-o-ome)

[Bridge]
Ooh-ooh-ooh-oooh, ooh-ooh-ooh-oooh
Ooh-ooh-ooh-oooh, ooh-ooh-ooh-oooh
