Leonemesis

I need some help too. I've been looking for the following song for SO much time! Nobody seems to know so far, so I think I need rock experts in this one. The song starts at 5:27 in the video below. (It's a test drive, I guess from an Argentinian TV show 'cause of the language) and it's played throughout the rest of the video. The chorus is easy to listen to at 7:21. I've tried by googling the lyrics but nothing happens. It sounds like a famous glam metal band, but I can figure it out. Help me please!
