Ha llegado tu mañana
Does this mean "tomorrow will come for you" like "the sun will come out tomorrow" type deal? Or is it more like "someone/it will come for you tomorrow". It has arrived for you tomorrow? Gracias
"Your tomorrow has arrived". Didn't I write this in one of the comments to your question about the song?
Anyway, I interpret it to mean that "this is your time", your future is now.
