MusicControlCenter (MCC) is a client application for mpd, the music player daemon (MPD). It's specially designed for handheld devices running WindowsCE/PocketPC (exp. Siemens Simpad), but can also be compiled as an native MFC-Windows-Application.
Very minimalistic and clean, which I generally like. In the same spirit it seems to ignore tags and go for the directory structure. I prefer that, too. Tags are just too chaotic and to much work to get right. However, I miss explanations for the control symbols. A tooltip would be really welcome. Could be configurable, preferably.
