The most notable difference here is clearly the volume slider, but under the hood I've rewritten just about the whole thing. Here is the current piamp code:

ratio = 100.0 / self.img_volume.width / 100.0

#100 / 256 = 0.390625
#If our touch/mouse location was 128 (right in the middle of the image), we want to set our volume to 50%, or 0.5
#Since 128 * 0.390625 = 50, we still need to divide that by 100 to get the percentage (or 0 to 1 decimal) that we want to use.
#Therefore, instead of 100 / 256 = 0.390625, we need a ratio of 100 / 256 / 100 = 0.00390625
#Now we need to find our x position in relation to the image, instead of the screen like it currently is

I've decided to utilize Tkinter and tkFileDialog for the file opening window, which looks like this:
To give you an idea on the state of the player:
Working:
- Volume Slider
- Previous Button
- Rewind
- Play/Pause
- Fast Forward
- Next Button
- Mute/Unmute
- Music Button (Open audio file)
- Movies Button (Open video file)
Not Yet Implemented:
- Show current selected file in text box
- Shutdown button
- Reboot button
- Equalizer button
- Video Playback - Currently player only plays audio for video files
In case you want to play around with the player (or the code) yourself, here is a zip file of the entire project:
Stay tuned - I'll be finishing up as much as possible tomorrow, and then I'm transferring all of this to the Pi and getting it installed in the car!
