Casanova

You, the hero, so many times
You've loved and didn't linger
Now my finger points at you
Another loserYou, an island on your own
Complete in every detail
Monumental, a precious jewel
Or just a foolInnovator, it's in your mind
And blood, I watch it simmer
I see you're courting more despair
No hope, not a glimmerNow you're nothing but second hand
In glove with second rate now
Now you're flirting with heroin
Or is it cocaine?
