Wrong or at least very confusing answer to a question on the exam.

There is not info that the song title is the primary key. By default, we assume that the sing id is the primary key. We would need a two-column primary key is something is wrong with the id column, namely, if it's not unique.
Why do you suggest we take the song's name in account at all?
