I know how the original poster feels.
It's not that I don't like the new music, it's just that I had so accepted the old song, so associated it with Pseudopod, that when it changed, I sort of rebelled against that.
It's like the last season of "Quantum Leap," when suddenly they whored up the theme song to, I don't know, make the show seem edgier or hipper or younger somehow. I hated listening to that last season's theme.
But hey, the new Pseudotheme isn't anywhere near as bad as that, and I don't mean to criticize it, just to say that it is jarring and unfamiliar. It's not a big deal, though, and I'll bet a couple months down the line, I'll be as into it as I ever was the old one.
I hope.
