You can't fake this music. You might be a great singer or a great musician but, in the need, that's got nothing to do with it. It's how you connect to the songs and to the history behind them.
The tango is really a combination of many cultures, though it eventually became the national music of Argentina.
No one was ever saved because his sins were small; no one was ever rejected on account of the greatness of his sins. Where sin abounded, grace shall much more abound.
