I totally agree on Ali Project just making the same song over and over again. Personally I name it ‘moonrunes – the song’ by Ali Project, since I can’t read the kanji anyway to great frustration of at least one person.

More importantly, a suggestion, request, or wherever the heck you want to put it if you had already planned to put it on the show:
“Kimi no Shiranai Monogatari (君の知らない物語)” by supercell from the show Bakemonogatari. (harhar,copypasteann)
That’s supercell as in the supercell who made a bunch of awesome songs with the Miku Hatsune Vocaloid, and even released a CD with the stuff. I only noticed that supercell did the ED song once I saw the ED animation of the third episode, which is equally awesome. I then proceeded to rip the song and put it on loop for several hours.

Fun show, keep on going Eryn.
