Convenience constructors don't work...

I've tried every combination that could possibly be correct here and none of them work.

if you are referring to the songWithSinger convenience constructor remember that convenience constructors are Class methods, not instance methods, so they look like

[Classname convenienceConstructorWithObject:object];

try

[Song songWithSinger:@"James Brown"];
