Undertale - Core

[Limeysoda]

This song is very dramatic but upbeat and it would be nice if it could be remixed to be more dramatic and upbeat,maybe something like a jazz fusion or classical arrangement would do this song some good.

Well, there may be a few choice tracks from the Material Collective Undertale album that could catch your attention. In particular, there's a chamber orchestra track for CORE (it's track #8), with some jazz flute in there for good measure. It's not as fast paced as you're requesting, but it's definitely something to sink your teeth into.

The alum has some great tracks on there, so don't stop with just that one if you're an Undertale junkie.
