I have absolutely way too many favorites... They change weekly, I think. So just have my top 5 for this week.
1. Sis Puella Magica!!
Why I like it: It's absolutely beautiful. The singers, the instruments, the pacing... It's all so wondrous.
2. At the End of the World
Why I like it: Anything by KOKIA is bound to be amazingly lovely, but I think this one beats out all of her other songs except Tears and Inochi no Uta.
3. Storm
Why I like it: Oh man, that beat. And Mai's vocals go well with the style of the song in general. It's dark without being negative, and that's probably why I like it so much.
4. The Day of Collapse
Why I like it: Sound.ave did an amazing job with this. The instruments work amazingly well, even if the song gets repetitive at times, but the ever-growing orchestra makes up for it.
5. Romeo and Cinderella (Zun style remix)
Why I like it: I was a big fan of the original song, and I love Zun's style, and this captured the unique feel of both. I will admit that I'd like more of the trumpets that Zun has, but overall it's a very nice song.
