Great song, I agree with the previous comment
It's about following a dream you have despite what others say about it. They're saying that as long as you believe in a dream and want to achieve it, you can't fail.
Mi corazon no falta translates to "my heart is not absent"
and luchare hasta el final translates to "I will fight until the end"
So they're saying that the band loves what they're doing and don't plan on stopping.
