He's a rapper, in cohorts with Ryan Lewis. However, unlike the stereotypical rap "music" that is popular today, he actually makes music. Real music, for music is meant to entertain, yes, but it's also meant to make you feel something.
He talks about things that are important, but many don't want to speak of or are uncomfortable about. For example, he has written a song about equal rights for all ("Same Love,") he has written a song about the horrors of addiction ("Otherside," "Neon Cathedral,") he has written songs about never giving up and going for your dreams ("Can't Hold Us," "Ten Thousand Hours," "Wing$,") and about how the music industry has become a bit rotten nowadays ("Jimmy Iovine.") Yes, he has also written songs that could be considered normal rap (kinda of...) like "Thrift Shop," "Castle," "White Walls," "Thin Line," and more. But that doesn't matter, because not all of his songs are like that(:
Macklemore and Ryan Lewis are one of my favorite music artists.
Person 1: "Hey, you hear that rapper on the radio yesterday, homebrotha?"
Person 2: "Oh, yeah, that was Macklemore & Ryan Lewis! Their rap actually means something, doesn't it!?!"
Person 1: "Yeah, man, they're da bomb!"
