Hmmm... perhaps.... but does this have anything to do with OOP per se? 

Alternatively, irrespectively of implementation flavor, how would you model your song-singer in an entity-relationship diagram [1]?

A song has zero, one or many singer? Potentially many, one would guess.

So, looks like a many to many relationship, no? Irrespectively of implementation language, no?
