Well, thanks to this discussion, I am going back to listen to the album for the first time in forever. The songs I remember liking are Disconnect, TWNAH, Warhorse, Dread, Silent Scorn, and Return to Hangar. I didn't much care for Moto Psycho, 1000 Times Goodbye, or Losing My Senses. I don't recall the other songs.
EDIT: And I have to say that Megadeth really has some outstanding non-album tracks throughout the years. Fully half of Hidden Treasures highlights that. Then you have tracks like Dread (even though it ended up becoming an album track), and Kill the King. I know they have a few more out there as well, but I'm not familiar with them.
