I am going to have to list them:
Get my drift?, STAR ROAD, Crescent Child, Naked Soldier, BRIGHT STREAM-All Nana Mizuki
Yuki Kajiura: odd world #3, I miss you, she is a witch, deep in grief, odd world #2, no more fear, and pretty much all the Madoka movie ost. I really loved it. More than the show ones I think.
Lacrimosa (live version from Live Best CD) - Kalafina
One of two songs that got me into them (and sucked me back into Yuki's music). And it's held up to re-listens better than the other song, Magia. Still love it.
LR Harmony - From New World. Unfortunately nothing from Aki Misato's new CD album grabbed me, so she seems to be one of the artists that needs to be combined with a good song or other good singers such as on "From New World" to really sound.
8/5/13: obbligato-Kalafina and Get my drift?-Nana Mizuki (Kalafina should do a cover of the Nana song, just because I can just see them having so much fun with it and it seems like one of their upbeat songs. I'd love it)
