We're not the boss of you. We know that. So we would never presume to tell you how to live your life (although you could stand to cut back on using the ubiquitous phrase "at the end of the day..."). But we here at Diffuser do know a thing or two about music -- considering our desks are buried beneath three solid inches of CDs and, well, it's what we do. So each week, we present you with a handful of new songs that we currently can't stop rocking on repeat -- some from artists you've undoubtedly heard of and others from those you'll hear about soon. Because, really, we just have your best musical interests in mind and, at the end of the day, that's why you're here. Check out this week's picks:

MANCHESTER ORCHESTRA

'Girl Harbor' from 'Hope'

Atlanta's Manchester Orchestra channeled their inner Radiohead (and, to a lesser extent, their inner Beyonce) this week when they unexpectedly released an album that almost nobody knew they were even working on. Although frontman Andy Hull alluded to the project last month on Get Up Kids singer Matt Pryor's podcast, it was largely a shock to fans when 'Hope' -- a full-length, stripped-down counterpart to this year's guitar-driven 'Cope' -- suddenly appeared online Tuesday (check out our review). Unlike that U2 album you never wanted in your iTunes, however, you're actually going to want to hear this.

DEATH FROM ABOVE 1979

'Right On, Frankenstein!' from 'The Physical World'

Back in 2004, raucous punk duo Death From Above 1979 burst out of Toronto to unleash their critically heralded debut, 'You're a Woman, I'm a Machine,' then promptly ceased to exist. Although the official break-up didn't occur till 2006, bassist Jesse Keeler said the band more or less came to an end the year before. But if a five-year hiatus is what it took to bring us the frenetic 'Right On, Frankenstein!' and the other cuts from their long-awaited, recently released sophomore effort, 'The Physical World' (review), we're tempted to say it was all worth it. Of course, all we had to do was sit here and survive 2012.

WEEZER

'Cleopatra' from 'Everything Will Be Alright in the End'

Whether you believe Weezer are radio-friendly throwbacks to a simpler time or the living embodiment of corporate rock, one thing is certain: they've got a new album coming out. While the lead single, 'Back to the Shack,' from the upcoming 'Everything Will Be Alright in the End' might be a little twee for your tastes, the second -- 'Cleopatra' -- is a feel-good track that packs a surprising punch halfway through. Of course, if frontman Rivers Cuomo gets his proposed Fox sitcom greenlit, you may not ever be able to look at him or the band the same way again. (Although Bryan Cranston did okay after 'Malcolm in the Middle.')

CYMBALS EAT GUITARS

'Place Names' from 'LOSE'

Speaking of the '90s, Staten Island's Cymbals Eat Guitars have never hid their affinity for the decade with the buzziest bins. Their third full-length, 'LOSE,' is filled with the sorts of fuzzed-out guitar sounds and angular melodies that bring to mind the likes of Pavement, Built to Spill and Modest Mouse. 'Place Names' begins slow and spacey before veering off into jangly, upbeat territory and finally building to a sonic wave of cascading rhythm and layers of vocals -- the kind Thurston Moore probably wouldn't hate.

YOU + ME

'You and Me' from 'Rose Ave.'

Unlikely co-ed duos are still all the rage in indie pop (ask Zooey Deschanel and M Ward of She & Him, who might be a little peeved about this act's similar name), but You + Me are about as unlikely of a duo as they come. Featuring singer-songwriter Dallas Green (of Alexisonfire and City and Colour) and Alecia Moore (otherwise known as Pink), the pair have released the first song from their upcoming collaboration, 'Rose Ave.' (written and recorded in six days) set for release next month. It's astonishingly listenable if not downright good.
