What do you mean as ROBLOX music?

 

I mean like all the roblox soundtracks made by roblox themselves.

 

I believe there are no songs made by roblox themselves.
For example, badliz made "The Great Strategy". but it's ROBLOX's theme song.
I'm no youtube wizard, but i think you need to ask the person that made a specific song to use it in your video.

 

try it, there are 3 possible outcomes

1. You get a strike, but that's no biggie, it'll expire, in a few months
2. You get your royalties taken from that video, but I don't you'll earn much from it.
3. You get away with it, then it's cool.

 

thank you everyone

 

Many YouTuber’s I watch have constantly stated they’re turning down the music to avoid copyright infringement.

Unless you made / or know the creator of the music it’s best you don’t try to have music from the game itself in your video but instead use a different music from a non-copyrighted source that would fit the similar feel you wish to give the viewers.
