How can I convert a mp3 file to a mp3 URL so I can play the song or audio clip in my game?

what do you mean?

You can download/upload sounds and music that you have on your device to be used in your games (in this case, an mp3 file). Remember, if the piece wasn’t created by you, always credit and ask permission from the author to avoid legal trouble should your game ever be exported.

but I have the free version does this matter?

no you can get it even with free version

how dont I have to make a mp3 url

you have to have a url

The URL has to have “.mp3” at the end, but only if that is the actual ending for the website. You can’t just add one in the end.

But say I want to get a song off of youtube how do I make that song into a mp3 url
