I have over 100 MIDI music files, mostly country western, the real country western, Walbash Cannonball, Whte Sport Coat, El Paso, Your Cheating Heart, Blue Eyes Crying in the Rain, Born to Lose, Coal Miners Daughter -- to name a few.
I like the WinAmp player. I have it set up to play my whole list of files continously. It plays in the background while I'm surfing or working. I find it very entertaining.
