FEIST, ''MUSHABOOM (POSTAL SERVICE REMIX)''
The Canadian folk songstress gets an electro makeover from Death Cab for Cutie leader Ben Gibbard's side project, the Postal Service, on this remix. The zippy take features new vocals from Gibbard. Buy it on iTunes
NICOLAI DUNGER, ''HUNGER''
A Swedish crooner who recalls Van Morrison at his bluesy best, Dunger offers the trumpet-pumping ''Hunger'' from his album Here's My Song..., which was recorded with indie psychedelia vets Mercury Rev. Download it for free at Rounder Records
BAND OF HORSES, ''THE FUNERAL''
Lovers of sky-high wails and sturdy guitar rock à la Built to Spill and My Morning Jacket should find these musical equestrians revelatory. Cloaked in reverb, their explosive anthem ''The Funeral'' is anything but lifeless. Download it for free at Sub Pop Records
