No.

When you say join on tracks, it uses the relationship "tracks", which in 
the case of the tutorial is defined via

__PACKAGE__->has_many('tracks' => 'MyDatabase::Main::Track');

So, it then goes to MyDatabase::Main::Track and finds out what table that referes to, which in this case is "track"

Any clearer?
