This is one of those samples that doesn't get boring or sound repetitive. It literally does not sound repetitive. If you are walking around doing housework, you could not tell it's just a repeating track unless you already knew.
As the other commentators have pointed out - your copyrighted song is copyrighted (assuming you didn't use anyone else's creative commons sound in it); this sound however is still licensed under a creative commons sample+ licence. This might seem unfair, but think of it this way. If you could retract a licence, then no one would ever be safe using a creative commons sound or public domain sound. Since there would be a commercial incentive to 'release' sounds into the public for free, and and seek out money from those who had used them honestly.
