I just happened to stumble over this one song that I really fell in love with, so I decided to share it with you guys.
It's probably the only Vocaloid song other than KOKORO that has managed to make me a bit teary eyed.

【初音ミク】 ライカ 【オリジナル曲】

The song's name is Laika, after the first animal sent into space, and also the first being to die in space. For those who don't know about this poor dog, you can read more about her here. So, yeah. It's a song about her. And in my opinion, it's pretty damn sad. I'll post the lyrics as well, which I got from here.

Quote:
What kind of ending will little old me have?
Looks like I’ll have to leave this place soon.

Compared to my other friends, I was just a little
more…talented. That’s all there is to it.

But whenever I got complimented,
I felt pretty glad,
since because I was more timid than everyone else,
I didn’t want to offend anyone or make them angry.

Being for the sake of everyone in the world and for the sake of the future,
it’s pretty amazing that they’re letting ME do this.
I feel a little, well, embarassed, about being given such an important duty,
But if this is what it came to,
I’ll hold my head high and go through with it, right now!

It became busy around me all of a sudden.
Is there a festival or something going on? That’s so nice!

It feels like everyone was nicer to me than usual.
I wonder if it’s my turn now? I’m ready for it any time!

In a box that was even smaller than I imagined,
I couldn’t move even a tiny bit.
I feel a little nervous, but
I’m going to do like I was told to since I’m a good boy.

“Bang” and “Crash”. Going at 8 kilometres every second,
I feel really, really scared! I couldn’t even tell what just happened!
But you know, no matter what, I’ll show you that I can handle this!
So later, when I come back home, please compliment me again!
Okay? Hey?..
