Here it is my first foobar2000 theme. It's pretty basic. Nothing fancy. It's aimed at people who like to keep the interface simple and clean and who spend time listening to their music rather than looking at their media player.
Some things you would need to set it up:
1. the latest beta version of foobar2000 (currently v0.9.5 beta 2) available here
2. foo_facets.dll available here
3. my theme file available here
4. (optional) the windows xp theme used in the screenshot is available here
After you have the foobar beta installed, copy the facets dll file into the foobar component directory. Run foobar then in preferences, go to default user preferences and click import theme. You just then need to select my theme file.
