I'd argue that your DB schema could be better.

In your album table name the column artist instead of artist_id. In the 
artist table just name the column id.

Then you can do $album->artist to get the artist object. The artist's id is 
$album->artist->id (although of course you can use $album->artist in some 
situations as stringification means it does the sensible thing)
