I hear sounds in games, but I never hear music in games such as SFOTH. I never head Wind of Fjords and the others. 

Is there any music automatically put into these games? How do I enable them? I'm playing on Win7 offline. I noticed that Wind of Fjords and The Great Strategy are in the files on Novetus, but I don't know how to add a sound service?

Do I need to build "edit" the rblx file of sfoth, and add the sound from there?

Theres no sounds for those games.

And you cant add since they cannot be played locally, which means only Roblox servers can run music on places. Sound engine was only introduced in 2010.
