Try removing the double quotes around %1.

But you don't need WACommand.
Winamp responds to its own command-line arguments.
You can see them by typing "C:\Program Files (x86)\Winamp\winamp.exe" /? in a command window.

This BAT file should do what you want:

code:
"C:\Program Files (x86)\Winamp\winamp.exe" /RANDOM=0

"C:\Program Files (x86)\Winamp\winamp.exe" /REPEAT=0

"C:\Program Files (x86)\Winamp\winamp.exe" /CLEAR

"C:\Program Files (x86)\Winamp\winamp.exe" /ADD %1

"C:\Program Files (x86)\Winamp\winamp.exe" /PLAY

To avoid seeing the command window flash open and close:

1. Create a Shortcut to the BAT file.
2. Edit the Shortcut properties to Run:Minimized
3. Send your file to the Shortcut.
