Spanish song titles and lyrics as slang

Can anyone identify phrases from Spanish-language songs that are used more by young people?
For example, there is an old song called "Hecho, es simple" (punctuation is not mine) that I think equates with "Been there. Done that" in English.

CAN SOMEONE IDENTIFY THAT SONG THAT GOES? LE DI UNA MEDALLITA, CON EL SIGNO DE LIBRA????
