Yeah I definitely agree with the statements from both you guys. Of course we will never know the truth of what happens behind closed doors. My own opinion at the time of them getting together was more that I was annoyed that she disappeared from the public eye and stopped making music for a while.
Judging without prejudice, I still never really liked his music at the time. But the "new" song that I posted above is actually good and I was impressed when I heard it and didn't know it was from him. As its obscure, I thought Alizée fans may not have heard it, and might find it interesting being that its related to their time together. But even without that context, I appreciate it as a song about feelings of nostalgia for the past, happy memories tinged with sadness that they are gone. I think we can all relate to that on some level
