Sounds like you have a textbook case of being bitten by the Lili bug!
The effect she has on people is funny, isn't it? I had a similar introduction to Alizée myself: one night I stumbled across a performance of J'en Ai Marre, and I just couldn't get it out of my head. The next day I felt compelled to watch it again... and again, and again. Never before nor after has an artist ever captivated me like this. There sure is something special about Alizée.
There is, of course, no cure for this madness. You can only help manage it through proper daily dosage of Alizée music and videos. The upside is that there is no happier affliction on Earth!
As for Stars a Domicile, I don't know of any subtitled versions of the 2003 episode, but there is a subtitled version of the 2001 episode (the end had me in tears!).
