Kalafina is awesome~! I'm a big fan as well.
Indeed.
Red Moon is SCREAMING for karaoke, lol. I love it. I listened it for the first time today and I'm already singing it (had to go through it a couple of times to get it at least *somewhat* right). But now I can go from start to end... I simple love it. Is there any instrumental version of Red Moon? That, with Serenato, Aria and Sapphire are my favorites. Hikari no Senritsu follows, and right after Oblivious and Love Come Down. I still haven't listened all the Red Moon album properly, just gave it a quick listen. Right now I'm too attached to Red Moon (the song)

Do you have more songs similar to ~Red Moon, Serenato, Aria or Sapphire~?

Too bad that now everyone is sleeping. Can't sing out loud

PS: And add to all that Natsu no Ringo :3
