Here's the break down.
2 models: song, artist
artists has many songs.
Is there already a pre-built method in rails that can check for
duplicate artists, and if the artist already exists, it will add the
song object instead of creating a new artist?
If there isn't I can write the method, would you write this in the model
or the controller?
Basically it would do this.
grabs the artist[:name] params, do a find_by_name, if it finds it, then
it will do concate with the song object, otherwise, it would create a
new artist id.
