Hi there!

Your code is almost correct, but there is a small bug in the condition if(records[id].hasOwnProperty(“tracks” === false)). The expression “tracks” === false will always evaluate to false. As a result, the condition checks if the object has the property false, which is not what you intend.
Change the condition to correctly check if the tracks property exists. Your hasOwnProperty() brace’s should be around "tracks". You have add also the condition part = false in it
