I used to use it a lot but switched to FB for its simplicity and customizability. I was also annoyed by the tenths of second.
is xmplay portable? kind of looks like it
it lacks music-organization features (though, those would only make sense for a playlist-centered player anyways).
XMPlay is associated with audio files, so single audio files and internet radio streams are opened in XMPlay. This way, opening a single audio file or stream is quick and does not mess up any of my playlist organization in Foobar.
