This is a song I wrote a couple of weeks back in Mario Paint Composer. I decided to make an MP3 of it using Frooty Loops and various soundfont players. It's made up of three different MP3 tracks squeezed into one MP3. I used Frooty Loops for the Synth Arppegios.
The drum track is played through a drum soundfont and the rest is played through a soundfont called "Airfont".
