From my first listening comparison, I gotta say that Milliontown benefits from the lack of whatever went into the CD mastering. The songs have a little bit more dynamic range (I'll take all I can get!) and the high frequencies are less "piercing." I can do a full frequency analysis later, since I love this sort of thing.
Yes that's basically what I was trying to say- I imagine that everything had to be remastered since some of the tracks had changed, and whatever Jem did or didn't do to master them is much better to my ears than the original CD.
In fact throughout the entire album I was swearing I could hear things that I'd never noticed before- making me wonder just how much tinkering had been done. (The exception being NMNY- I wonder if this is the only track which retained its original mastering?)
I'm assuming it was actually just the start of Milliontown, the start of Hyperventilate and the end of BLM that have actually been updated- but the whole thing had me hearing all kinds of little guitar and keys parts which were just a giant piercing mush before.
Might just be "first listen" syndrome but this seems like an absolute winner to me.
