On this week's All Songs Considered, we've got several new favorites including Bob Boilen's No. 1 discovery of 2016 so far, Lucy Dacus. Robin Hilton shares songs by several artists he thinks are about to release their best albums yet, including Santigold and Ane Brun. Also on the show: Iggy Pop brings back his Bowie-inspired swagger with help from Queens of the Stone Age's Josh Homme, French musicians Adan Jodorowsky & Xavi Polycarpe channeled their recent breakups into a big '70s-flavored pop song, PJ Harvey returns to her original rock sound and electronic artist Ital Tek reflects on his love of guitar drones and distorted electronics. Plus, rapper Macklemore asks a lot of difficult questions about race and responsibility in the song "White Privilege II."
