The truth is, lots of people in the black community like M's music. He is respected as a singer and lyric writer, lots of them know about music history and like that M is his own man and beyond the curve- Prince was a big M fan
He doesn't wow them like Bowie did and lots think hes a bit of a "Mommys boy" but he is respected.
As for the hip hop community, same kinda thing. Lots see he is way beyond them with words (Or used to be), they can see he comes from streets much like their own (UK hip hop people)
So he is respected by the brighter people in the hip hop community - like PE, BNP , Tribe, De La Soul etc
Snoop is a fan of M's , Ice cube isn't a fan of him - no loss M is worth a million of him, hes very basic and homophobic .
Mainly though, he is unknown in that world and most wouldn't know him, if he handed them a fly gold chain
As for those Supreme T-shirts, they are just people on a brand, most don't know M or Lou Reed who wear that Supreme stuff - which Im proud of, anyone who pays loads of money for supreme "limited edition" stuff is a moron.
Its such a con . Its kinda sad M even got involved
