geraineon, 
Thanks youtube for recognizing I am really digging myself back into Vocaloid pit.
Here's a nice song I have not heard because I've been out of Vocaloid for ten years so I am still discovering new old things:
Life Hates Us Now, covered by Mafumafu, produced by Kanzaki Iori: https://www.youtube.com/watch?v=eq8r1ZTma08
It's about living on despite everything.
