Hi! Did you have any problems publishing it on Steam? I wanted to download the audio, but I'm worried about the rights!
The license requires a link and Steam hates it. I had to remove all the sounds and then immediately after that I had them in my game. Trust me there are other options and they are better than having to remove all the sounds after being rejected.
You can pay after download, which is a death sentence for Steam, they don't allow any payments from outside of Steam.
