Best new songs this weekend: Lawrence Rothman & Marissa Nadler, Elder...

Isaiah Rashad returns with 'Why Worry', his first new song in 4 years, a good slice of soul-sampling hip-hop; Sigur Rós’ Jónsi shared his hypnotic new song 'Exhale'; Elder dropped their new album 'Omens', containing a great atmospheric prog song 'Halcyon'; Johnny Flynn - who plays David Bowie in new movie 'Stardust' has released 'Good Ol' Jane', intended to sound like an early, lost Bowie song; iLe and Natalia Lafourcade play futuristic Latin music on 'En Cantos'; Ben Gibbard played a nice piano cover of Nirvana's 'All Apologies'; Earl Sweatshirt's first single of the new year is a lazy 'Whole World'; just a beautiful song 'It's Hard to be Human' by Lawrence Rothman, featuring guest vocals by Marissa Nadler and the MUSYCA Children Choir.
