Anything else.
You not only used "a pony", it was based around that thing.
how about literally anything else ever
as a longtime ytpmv fan and one time maker(
eh), i will say that even though i really don't care about that show, pony ytpmv's often sound really good because good ytpmv sources rely on soundclips that can be pitch shifted easily, are melodic and sustain the same pitch, and mlp is chock full of that.
like listen to
this BeaT song and then listen to
this ytpmv. it sounds forgetin great, and like 90% of that ytpmv is no bgm which is really difficult to make sound good, trust me.
that being said, they almost work too well, which is why when people make ytpmv with wierd ass sources i respect em more.
check this out, this might be my favorite ytpmv
