I just realized that this song could be the italian version of J'en ai marre. Lol
The title means bath tub and the "atmosphere" is happy and playful, whereas Alizée's
bain de mousse is a place where you forget all your problems.
It probably won't have the same effect on you, but this is one of those song that were very popular when I was a child and it is weird to find a connection to Alizée. It was released in 2000.
