You're not nuts. I used to wear Jovan Musk regularly and found it to be a nice scent. A little odd, but nice. Sometimes it smelled like dandelions and pungent musk, very oddly green and '70s. Other times it smelled clean, like freshly-laundered clothes. I could never quite figure out exactly what that one was supposed to be. It does, however, have a little bit of a cheapy-cheap feel, particularly in how the notes separate and the scent evolution accelerates. It's like it goes from being a murky floraly musk at first, to a very rapid drydown of musk and spice. It happened faster and faster every time I wore it - maybe because the air in the bottle touched off the balance of the top notes. But other than these little things, it's an all-around good scent imo.
My favorite Coty (not Coty Prestige) scent is Aspen, however. I think that one is better than any of the Jovans, although I do like Black Musk, too.
