Nice. :)
I liked it - nice, clear music that wasn't cluttered with background noise, unlike some of the rips I've heard of this stuff before.
A couple of suggestions though, which you might want to consider if you submit a sequel:
First, unless it has some voices and such, you should probably call it a jukebox - I know it's the same layout as a soundboard, but it would be easier for people to know whether or not to load it if it was called a jukebox or something.
Second, you could probably squeeze some more tracks in there before you hit the size limit. Not too many, but even one or two would fill it out a lot more.
The only other thing I could suggest is a couple of different backgrounds to choose from - I actually really liked the simpler approach you took with the presentation, but some people like more bells and whistles even when they're entirely unnecessary.
Anyway, it got my protection point because what was there was very well-executed; I hope you come up with an expanded version of this, because you apparently know what you're doing and I think you would make a good job of it. :)
