Music ID help

I found a lot of great songs across many roblox games, however, is there any way to get the music ID of them and bring it into a different game? Specifically I want the music ID for Fisch.. I know some people have already asked this question before but idk exactly how to check if they are now private or what do I even have to search for it to pop up, etc.

If anyone can, please help finding the music ids for it- Thanks!
