The song from the Cingular commercial
La donna é mobile
Qual piuma al vento,
Muto daccento - e di pensiero.
La donna é mobile!
Qual piuma al vento!
Muto dacceeeeeeeento - e di pensiero.
The lady is wishy-washy,
What a feather to the wind.
She ain't no talker - she ain't no thinker.
That lady is wishy-wash!
A feather in the wind!
She ain't no TAAAAAAAAAALKER, OR NO THINKER!
There are different translations of this song online, so I decided that my translation would be best. Trust me, it's accurate, although parts are loosely translated.
