Over at Diffuser.fm Radio, our totally boss online radio station, we're obsessed with new music, and this week, we've padded our playlist with six fresh tunes. Need an alt-pop pick-me-up? Take solace in .fun's anthemic 'Carry On.' Pop-punk more your speed? Marvel as Green Day hijacks the Supremes' 'Can't Hurry Love' bassline on the zippy 'Stray Heart,' the lead single from their forthcoming ‘¡Dos!’ album.

Rounding out this week's adds are AC Newman's typically obtuse and tuneful 'Encyclopedia of Classic Takedowns,' Welsh trio the Joy Formidable's surging 'This Ladder is Ours,' Placebo's big and moody 'B3' and Titus Andronicus' brawny, brainy 'In a Big City.'
