I havent done alot of work in relations recently but from what ive seen and used the relations module will probably be the way to go to establish the relationship longer term but references gets thejob done today for you. You might want to consider using a ctools multistep form with an onscreen link on the "add album" edit page that links to "add a track modal/multistep" and have it return the nid that is created for relation to add it to the relation on the node youre making in the last step.
I think this might be best handled as a custom multistep form that takes the albums initial data repurposing the node edit form, track data doing the same and then saves the entities in the correct order but hopefully someone has a more concrete answer for you that has been down your path. Good luck and please let us know how you settle it. -- Michael Favia [email protected] tel. 512.585.5650 http://www.favish.com
