I apologize for this:

I didn't realize that when you unzipped the files, it just spilled out mp3s. On my mac, since I'm using the unarchiver app, it automatically makes another folder and puts the mp3s in there. Although it doesn't matter in the long run, I realize it's an inconvenience so from now on I'm going to be putting the files in a folder, then zipping that folder so when you unzip it, you will have a nice folder full of mp3s. Sorry again!
