I've always thought 'apart from the national anthem, what your favourite song' would be an insightful interview question for Trump - I guess because it's so hard imagine him with a hobby that isn't about power.
He plays Hotel California a lot at Mar-A-Lago. A lot people don't know that he picks the music they play there, and sometimes actively DJs. This is not a joke.
He'd probably say The Apprentice theme tune "For the Love of Money."
