I like Dream Theater's first album. It's just Charlie's voice was a bit strange for them. Otherwise most of the songs are excellent on WDADU. I wasn't even aware Dominici was doing anything in music again. I'll have to check that out.
There's nothing wrong with putting Pyromania on your list. The album rocks and I still listen to it today. I was five when that album came out and Def Leppard became my favorite band for a little while because of Pyromania. It's my favorite Leppard album. The only thing is you picked one of the two weaker tunes as the 'featured track'. I would've gone with Die Hard The Hunter.
