std::string maria{"\
[Verse 1] \
The sun ablaze as Maria's foot touches the surface of sand \
On northern land, as human contraband \
Some rico from Jalisco passed her name to the Boss \
She stuffed into a truckbed, she clutches her cross \
Here comes the exhaust and it rips through her lungs \
She's off fast to the pasture, like cattle she'll cross \
Degree 106, sweat and vomit are thrown \
And she prays and suffocates upon the memories of home \
Of Yanqui guns for blood, debts on the loans \
Of smoldering fields, rape, rubble and bones \
Of graves hidden, trapped up in visions of war \
Of nothing, no one, nobody, no more \
[Chorus] \
These are her mountains and skies and she radiates \
Through history's rivers of blood, she regenerates \
And like the sun disappears only to reappear \
She's eternally here \
Her time is near \
Never conquered but here \
[Refrain] \
To tear away at the mask \
[Verse 2] \
And now she got a quota, the needle and thread crucifixion \
Sold and shipped across the new line of Mason Dixon \
Rippin' through denim, the point an inch from her vein \
The foreman approach, his steps now pound in her brain \
His presence, it terrifies and eclipses her days \
No minutes to rest, no moments to pray \
And with a whisper he whips her, her soul chained to his will \
\"My job is to kill if you forget to take your pill\" \
Her arms jerk, the sisters gather 'round her and scream \
As if in a dream, eyes on the crimson stream \
Numb as her wrists spit shots of blood to the floor \
I am nothing, no one, nobody, no more \

[Chorus] \
These are her mountains and skies and she radiates \
Through history's rivers of blood, she regenerates \
And like the sun disappears only to reappear (Maria) \
She's eternally here \
Her time is near \
Never conquered but here \
[Refrain] \
To tear away at the mask \
Away at the mask \
To tear away at the mask \
[Bridge] \
No minutes to rest \
No moment to pray \
No minutes to rest \
No moment to pray \
No minutes to rest \
It eclipses her day \
Just a moment to pray \
[Refrain] \
To tear away at the mask \
Away at the mask \
To tear away at the mask \
To tear away at the mask \
