Extbase can build the whole object graph for you as long as you hold the 
naming conventions or provide a mapping rule. But to be honest, I have 
no working example for this case. The following code might point you in 
the right direction.

class Tx_CD { //shortened version ;-)

  /*
   * @var Tx_Extbase_Persistence_ObjectStorage<Tx_Track>
   */
  protected $tracks;

  [setter getter]
}

class Tx_Track { // works with foreign_key

  /*
   * @var Tx_Record
   */
  protected $record;

  [setter getter]
}

class Tx_Record {

}

Let's see what we can do for the next version of Extbase. ;-)
