Actually, putting your own music, or radio traffic recordings, into the game's radio folder is something we don't make a fuss about.
As long as it's simply adding some music or other sound files and not actually going into game files and altering things that are not supposed to be altered, we'll look the other way.
Removing any files from that folder means that you'll have install the game again if you want to revert though, so the only tip I'd add would be to back those files up instead of deleting them, if you ever want to have them back but without the need for a fresh install, but other than that there's no problem with this.
In fact, many people have done this in the past. But thank you for sharing this anyway, XxEMPxX.
Obviously, downloading copyright protected music is another thing, it's usually not permitted, but that has nothing to do with Shipsim as such of course.
