I'm really not sure how a theme can be in beta, but this one sure is. I was looking around at the themes, and I couldn't find one that I really liked. A lot of reading and about 6 hours later, this is what I've came up with. This is the very first theme I have ever made, and I have only tested it on my current window setup.
One question though for any other theme creators out there. Is there a way to customize the highlight color of the menus (File, Edit, etc.) on mouseover? All my menus appear to have a blue highlight (except for the items that are disabled).
If anyone has any problems with other window configurations, I'll do my best to try and fix it.
Please excuse my poor organization. I'm working on that project now that I have a better looking interface.

1. Download the file and copy it to C:\Program Files (x86)\MusicBee\Skins\ (Any subfolder will work, or just the root)
2. In MusicBee go to View>Skins>(Path) Path will be the location to the theme that you saved in step 1.
