Short and sweet again today—MusicREDEF will be back at full strength on Tuesday—and we'll dedicate this one to REGGIE LUCAS, who died Saturday at age 65. You can assign a number of musical descriptors to Lucas: guitarist, producer, songwriter. But good luck assigning a genre to a man who was an essential piece of MILES DAVIS' early '70s electric band (and de facto co-composer) and went on to produce most of MADONNA's debut, one of the landmark pop records of the 1980s (while he was at it, he wrote "BORDERLINE"). Remember when musicians could walk through walls like that? Actually, they still can, and do. While the industry (and, to be fair, people like me) are assigning boxes and borders, the best artists, and even some of the not-best artists, are following their muse wherever and whenever it takes them, and god bless them for that. RIP Mr. Lucas... XXXTENTACION's banishment from SPOTIFY's official playlists has reduced his daily streams by 17 percent in the US and could cost him $60,000 per year, BILLBOARD reports. His terrestrial radio plays are also dropping. Another target of Spotify's new policy on "hateful conduct," TAY-K, responded by creating his own playlist on the service. Playlist description: "Rugrat Music is a playlist dedicated to help advocate an artist's ability to freely speak on their environments." More than 15,000 followers as of Sunday night... TROY CARTER says he is very much still at Spotify, in case you were wondering... BILLBOARD MUSIC AWARDS winners and performances... That cellist... What CHELSEA MANNING is listening to these days.
