Impressive work so far. It's good to be able to look back at my old FC-tracks in a completely different light of day, and the replayer does it all nicely as well.
In case you haven't done so already, you should really have a chat to BuZz, who runs the Exotica site, to discuss usage of his search engine for information about tracks and all other things surrounding the music since it's amazingly performed and I think you'd make it quite easy for yourself to get to that info to talk to him.
Also, since I was one of the members of Musicline and have control of the sourcecode for it, just howl to me if you want it to study for implementation.
Keep it up!
P.S. How quickly do you get deleted from this board? I know that I've been registered here before, but that account had apparently been deleted... D.S.
