MIDI Music Sites:

Most of my games use common MIDI music files for the background and "win" music. On the older games these were stored separately in each game folder (and still are for some of the older games, like Dinner With Moriarty, Honeycomb Hotel, Floyd's Bumpershoot, and Knarly Works). Most of the other newer games store their MIDI music files in a common MUSIC folder (C:\EKS\MUSIC by default). If you'd like to add your own music files to the newer games, you can do so by simply copying them into that folder, and then selecting them for play in the games of your choice. Here are several great sites from which you can download additional MIDI files in a wide range of styles:

Kunst Der Fuge Composers' Index - Over 8,000 classical MIDIs by a very wide range of composers for you to download.
Ragtime MIDIs by Warren Trachtman - Download ragtime piano pieces by Scott Joplin, Jelly Roll Morton, Eubie Blake and others.
