Le Portrait De La Petit Cossette. I don't know whether it's me loving how dark and enchanting the anime is, or what, but I find its ost to be fitting. I even tried figuring out where the songs might play during the rp, lol. I believe the composer of this anime also did .hack//sign music, just saying in case you noticed the similarities in the tunes/melodies.
Track 1:
Main Theme: Cirque du Noire's victory theme. Hazzah!
Track 2:
Somewhere I Belong: Oooooh, I feel a Sil x Alexander, or, Sil x Loyal, them finally come to terms with their lovey dovey feelings. -gets shot-
Track 3:
Moonflower: A love that weren't there. A sorrowful tune. Could be used to summarize Sil's harsh treatment in the circus.
Track 4:
Sadness: Anyone thinks of Sil's mission thread? Her underlings are on the mission of turning Sil's frown upside-down. ;D
Track 5:
Regret: Icarus fell and learns that he lost his leg. Devastating. :<
Track 6:
Love Pain: Sil uses the power of the pendant to turn people into animals. Oh noes! O_O;
Track 7:
Unhallowed- Totally Mrs. Puppet's theme.
Track 8:
Leave me Cold: Iris being picked on by other people because of her hair color.
Track 9:
Breakdown: The death of Alexander Pierre. Or, Ace finally breaking down. xD
Track 10:
In a Beautiful Morning of May: Opera... I could only think of Sil's Fae species for this one. :<
Track 11:
A Prophet's Dream: "So... You want to join the circus? I welcome you to -
insert circus name here-."
Track 12:
Undertow: Sin finally get to do what she planned to do, and being successful at it. O_O;
Track 13:
Float: Sil's sleeping. She's setting herself to a very bad nightmare flashback.
Track 14:
Fake Jewel: Meldellevo's character theme. Haughty yet dark.
Track 15:
Silent Ceremony: The song picks up at 1:55-ish. Sin's character theme.
Track 16:
Evocation: Sil's creatures are on the loose! The room's now in chaos, and people are getting hurt! Sil: "That's not supposed to happen!" D:
Track 17:
My Love, So Sweet: Sounds like a nostalgic song. Fits anyone with a sweet/wonderful childhood (hello Ace).
Track 18:
Houseki: Love this song, but no idea where it'll go. D:
