Believe it or not, almost 7 years after its initial release, the Foobar2000 v1.0 Beta is finally out, and with it comes a large list of changes. Most of them are much-needed interface fixes, but there is the welcome addition of built-in support for the streaming of Windows Media formats (ASX/MMS/RTSP). Other than that, it's much of the same.
I don't use it, I use WMP, but I know many of you do so maybe this is relevant.
