Aha I've been subbing vocaloid videos a lot lately (dunno Japanese so I just put subtitles on the vids that don't have any but the translations are available. I sorta remember some Spanish so I've translated one from the Spanish translation and working on translating another).
Been wanting the translation for this for a while, woo found someone to ask and subbed it :)
Subs Added more subtitled videos here, and a couple duets I mixed together xD
And a couple covers I like that I want to pair with the PVs, I got permission from one person on YT though can't really contact anyone on nico but hopefully it'll be ok and I'll take those down if they ask xD;
