Best new songs today: Vijay Iyer Trio, Beck & McCartney, Mysie...

Vijay Iyer Trio share some groovy piano virtuosity with 'UnEasy'; Paul McCartney seems much younger in a Beck remix of 'Find My Way' - the younger musician got the idea for the mix remembering seeing McCartney dance; supergroup Satanic Planet (featuring members of Slayer, Locust and Planet B) share their first song - a, obviously, satanic industrial electro 'Baphomet'; Mysie shares an R'n'B velvet 'Keep Up With Your Heart'; Luminous Kid shares an emotional same-sex song 'Mountain Crystals’ featuring spoken word by Phoebe Bridgers; U.N.K.L.E. just go dancing on 'If We Don't Make It'.
