[LAU] Sound Board for Linux?

[Michael Afflerbach]

I am looking for some instant sound board software that I can install on 
a Linux machine.

Basically, I need a GUI interface with buttons (or rows of buttons) 
where I can play out MP3s in rapid succession out the soundcard.

Here are good examples in Mac OSX

or in Windows

But for the life of me I am unable to find a Linux soundboard program.  
Shouldn't be complicated and I must be a moron, so can anyone point me 
in the right direction?

Thanks in advance,
