Hi @adnan1.

There are a few bugs here in your code.

On this line, you have record instead of records.

You have an extra ending curly brace here:

}
return records;
}

I would remove the one right before return records since you need to always return the records object.

Also, this line:

records[id].tracks.push(value)

is outside of where it should be. It’s only applicable for the tracks property.
