All the Atelier games!! ...Oh wait I'm going to donate all those, but I'm going to list a few anyway... I'll list other things first, though~ And also Higurashis and Uminekos, I will donate all those if no one else does. orz ...And Slayers....

01) World Destruction/Sands of Destruction anime OP - ZERO, No one will care about this one but me, but I think it's a pretty cool opening!
02) Noir OP - Coppelia no Hitsugi
03) Umineko no Naku Koro ni Chiru PS3 Catch-all OP - Inanna no Mita Yume, It might be weird to list this Umineko OP of all OPs buuuut... I joined Credits, my first TCG juuuust to collect this because I ran into it while google searching Umineko stuff THIS OP IS WHY I PLAY TCGS, so I'd really like a Tones deck. I'd be donating it this month if I didn't want my Atelier decks. XD
04) Fate/Extra CCC OP - Sakura Meikyuu, I... already have images for this one but it's pretty SO.
05) Mahou Shoujo Madoka Magica ED2 - Magia, I hope there's enough images to get out of this because I love it so much. ;_;
06) Baten Kaitos OP - Nadir's Whale, Okay I just want Baten Kaitos decks in anyway I can get, I can't remember if there's a version without subtitles though... Also warning: ~amazing~ voice acting within. The Japanese version was also in English but with different English actors and it was pretty ~amazing~ voice acting too.
07) Disgaea 2 OP - Sinful Rose, my favorite Disgaea OP~
08) Ar tonelico II OP - Singing Hills ~Harmonics FRELIA~, I plan on donating the 3 Ar tonelico OPs together, but this one is my favorite~

I'm only linking 2 Ateliers or else I'd go crazy:
09) Atelier Shallie OP1 - Rusty Sky, I have a half finished fake deck for this I really want to finish, but I'm donating it this month and really can't wait to see how it turns out~
10) Mana Khemia OP - Run for Your Life

THERE ARE SO MANY OTHERS but...
