Try this one for data...

function get_album_data() {
    $this->db->select ( 'album.*,cat.*,s_track.*' )
        ->from ( 'albums as album' );
        ->join ( 'categories cat', 'cat.cat_id = album.cat_id')
        ->join ( 'soundtracks s_tracks ', 's_tracks.album_id = album.album_id');
    $query = $this->db->get ();
    return $query->result ();
}

while for datum try this...

function get_album_datum($album_id) {
    $this->db->select ( 'album.*,cat.*,s_track.*' )
        ->from ( 'albums as album' );
        ->join ( 'categories cat', 'cat.cat_id = album.cat_id')
        ->join ( 'soundtracks s_tracks ', 's_tracks.album_id = album.album_id');
    $this->db->where ( 'album.album_id', $album_id);
    $query = $this->db->get ();
    return $query->row();
