Who the heck is Macklemore? Seriously, I have no clue who he his and I’ve never heard his music.
Only one I know of played 2nd base for the Rangers in the 1990s.
Do what I do - whenever you hear the name of some musician you don't know, just assume he's some asshat enjoying 73 minutes of fame on pop radio. You don't have to know who anybody is, they'll be gone before it's important.
