This week, Lizzo continues dropping hits in advance of her new album — this time featuring none other than Missy Elliott on “Tempo.” Dance duo Sofi Tukker try a new sound on recent release “Fantasy,” ahead of their next project. Rising country singer Kassi Ashton goes introspective on the intimate, haunting acoustic ballad “Pretty Shiny Things.” Kailee Morgue brings in Hayley Kiyoko for the emo-pop bop that is “Headcase,” a track that traverses dark territory with a wink.
