I've just listen to the sound clip, well better late than never.

I gotta say I like what I've heard, the music is more Rock orientated and Alizée sounds as good as ever but still a bit different from other songs that she's sung. I believe with the new album, Alizée will show us her versatility and we are going to be in for a treat!
If this much fuss is being made over a 20 sec clip on forums though, I think when Alizée releases the video to this and the new album comes out, this forum won't be able to handle it!

Btw. It looks like I was right about the Fifty Sixty part being sung in English and Alizée didn't dissapoint.
