Using Rails I'm trying to get an error message like "The song field can't be empty" on save. Doing the following:

validates_presence_of :song_rep_xyz, :message => "can't be empty"

... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly. How can I change the title of the field itself ? I could change the actual name of the field in the database, but I have multiple "song" fields and I do need to have specific field names.

I don't want to hack around rails' validation process and I feel there should be a way of fixing that.
