Apparently when I did the last round of renders, something went wrong in the two-step process that I use. It played fine on my computer, which led me to initially believe it was Youtube, but I re-did the second phase of the render and re-uploaded it and voila, normal colors!
THEREFORE! Expect about 8 new pony songs soon!
Basically, by the time I'm done uploading, I will have every single Season 2 song on Youtube, including a compilation video with all of them, referencing their respective episodes.
I've had them done for a while, but this Youtube-color-eating thing was preventing me from having decent uploads.
Back from pandas for a bit, need a break from questing.
