Wow, I'm an idiot. I used a program called Tag&Rename, and clicked the wrong button. The end result was 300+ songs renamed to "- (1)", "- (2)", etc. Is there any way to undo this? I don't want to system restore, as I did something right before it, that took me quite a while to do. Also, these songs have no tags in them. I was trying to add them, but as you can tell, I failed miserably.
