Río y no sé porqué

I live and I don't know how long
I search and I don't know what for
I die and I don't know when
I laugh and I don't know why
I laugh and I don't know why.

I march and I don't know where to
How can I even know
Luck is hiding from me
I laugh and I don't know why
I laugh and I don't know why.

I keep and hang my dreams
On a piece of wall
I don't understand this
I laugh and I don't know why
I laugh and I don't know why.

I let time pass by
I've got nothing to lose
They say I'm not sane
I laugh and I don't know why
I laugh and I don't know why.
