When roblox copies a gear, they make it diffrent enoguh so they can't sue, although close enough the average player can obiously tell what game it was basesed off of. Eathier this, or they ask for permission just to be safe. Schools have to pay money to the composer of the music so they won't be sued, if he is dead, it's eather the sponsors, family, etc.
