What do Trump and Biden's musical choices say about them?

Songs that Donald Trump plays on his campaign are mostly classic rock that project power and combative self-confidence, like Queen's 'We Are The Champions', Tina Turner's 'The Best', and Survivor's 'Eye Of The Tiger' (containing the lyric "just a man and his will to survive"). BBC sees Trump's choice as one "based on how they feel, rather than a scholarly analysis of the lyrics". Joe Biden mostly goes for the lyrics, like with The Staple Singers' 'We The People', or for feel-good songs like Bill Withers' 'Lovely Day' or Jackie Wilson's 'Your Love Keeps Lifting Me) Higher and Higher.
