I just remembered another reason the highlighting was removed... other than the info window text, it's not currently possible for XMPlay to get the download progress from plugins that use their own download routines (eg. XMP-WMA).
It would be great if input plugins could give download progress, and other cool stuff such as loop points! The plugin wouldn't need to handle looping itself if it needs custom loop points. One problem the vgm/vgz plugin has (apart from being for Winamp instead of native) is that looping is implemented by making the song longer. So you tell it to loop 10 times and there you have an 11 minute song... Far better if it could give the music as-is and let XMplay loop it. Oh well I went off-topic didn't I?

Missing the download progress bar too...
