probar means taste, not probe.
Ay, me siento tan suerte > me siento afortunada or 'con suerte'.
Me pondrán a prueba > They might/will test my heart.
Sometimes these are simple things > A veces son cosas tan simples

Suggestion to turn 'igual' to 'compara'. So: "Nadie mas compara".
ok, there's at least one line I didn't get :(
