CakePHP .find to return multiple HABTM relationships - cakephp

Question

I have a Model call Playlist.
Playlist has a HABTM with Track
public $hasAndBelongsToMany = array(
'Track' => array(
'className' => 'Track',
'joinTable' => 'tracklists_tracks',
'foreignKey' => 'tracklist_id',
'associationForeignKey' => 'track_id',
'unique' => 'keepExisting',
'conditions' => '',
'fields' => array('id','title','version'),
'order' => 'TracklistsTrack.timing'
)
);
Track has an HABTM with AppUser
public $hasAndBelongsToMany = array(
'Artist' => array(
'className' => 'AppUser',
'joinTable' => 'artists_tracks',
'foreignKey' => 'track_id',
'associationForeignKey' => 'artist_id',
'unique' => 'keepExisting',
'conditions' => '',
'fields' => array('id','username')
)
);
Now, i would like, when i write this
$tracklist = $this->Tracklist->findById($id);
to get for each tracklist all the tracks (and this does work as supposed to), and for every tracks all the AppUsers (cascading).
Mind that if i write $this->Track->findById($id);
i can actually get the AppUsers related to the track
Any idea to have this out of the box thanks to my diligent naming convention ?
Thank you

If you have define the correct relationship in your model, I would suggest using CakePHP containable behavior.
http://book.cakephp.org/2.0/en/core-libraries/behaviors/containable.html
All you need to do is to include the behavior in your model and put the following in your controller
$this->TrackList->contain(array('AppUser','Artist'));
