Undertale STO

It's a beautiful day outside...
This is just a little song I did for fun. I just took megalovania and a metal version of it and put the 2 together. I added a beginning part and little effects here and there, but most of it was the cover. 
The metal cover can be found here:

On this song I've actually met the limited number of downloads that I'm allowed to have on a track. So now I have to use this other method for you guys to be able to download the song. Go to this website: http://scdownloader.net/ and enjoy! ^-^
