Ok, now you've got no reason to complain anymore - the BASS Sound System for ViRC is out. mp1/2/3, OGG Vorbis, MOD (XM,IT,S3M), Shoutcast streams and much more, directly from within Visual IRC.
Updated: Bug fixs and added a few more functions.
This is a beta release, meaning the CD playback support isn't in yet, neither is the file request service. And PLEASE read the README.TXT
