This week on Diffuser.fm Radio, our totally boss online radio station, we've got new music from all over the world. Just-added tunes include Canadian sister duo Tegan and Sara's 'Closer,' the synth-driven lead single from their forthcoming seventh album; English folk-punk troubadour Frank Turner's rousing 'If I Ever Stray'; and two songs by Scottish acts -- Frightened Rabbit's somber 'State Hospital' and the Twilight Sad's gloriously noisy 'Dead City.'

Holding it down for the United States are Portland's Blind Pilot, who float good vibes on 'We Are the Tide,' and Denver risers Churchill, who check in with 'Change.'

Hear all six new tunes -- as well as hundreds of other great songs -- by clicking the link below.
