Can you please add an Windows Media Player plug-in cause WMP library can't read tags for FLAC, Vorbis, ape, ...
And if you'll consider this please add a 64-bit version too (for the plug-in) cause on 64-bit windows it's a must for Windows Media Center which it's using the 64-bit version of WMP
An example of such plug-in is WMP Tag Plus http://bmproductions.fixnum.org/wmptagplus/
