Don't forget the Nightingale song, One of the Lonely Ones. Maybe Dan is actually a vampire, and he's always referencing the moon because he doesn't see the sun that often.
I think it's pretty cool that one of Dan's favorite albums is Hold Your Fire. Most Rush fans overlook that album and most of their late 80's synth phase.
Invisible is probably my favorite too. The production and Dan's vocals are great. Atlantis Rising was one of the first songs that really got me into Nightingale.
