i need a script that plays a certain music when a certain block is touched?

and it shouldnt stop playing the music until you stop touching the block

We're here to help, not give scripts. But I have a suggestion on how you would do this.

You would need to use the Touched event, and after the player touches the brick a sound will play. Here is an example:

brick.Touched:connect(function(part)
	if part.Parent:findFirstChild("Humanoid") then
		-- do code
	elseif part.Parent.Parent:findFirstChild("Humanoid") -- just incase the accessory hit the brick.
		-- do code
	end
end)
