#5 solo te voy a contestar con esto:

It's the final countdown
The final countdown

Oh, we're heading for Venus (Venus) Mars (Mars)
And still we stand tall
'Cause maybe they've seen us
And welcome us all, yeah
With so many light-years to go
And things to be found (to be found)
I'm sure that we'll all miss her so

It's the final countdown
The final countdown
The final countdown (final countdown)
Oh, oh-oh-oh

(tanto pelo no es sano)
