Unlimited Sunshine? Maybe, but shadows fell on New York's Terminal 5 Wednesday night as Cake performed an ode to the Prince of Darkness, whipping out a cover of Black Sabbath's 'War Pigs.' Cake's take on the classic -- destined to become a fan favorite of their live sets -- is offered up on their latest release, 'B-Sides and Rarities.'

Sabbath they are not, but who is? In the absence of Ozzy, let them eat ... well, you know.

'The Way I Am,' Ingrid Michaelson
From 2007's 'Girls and Boys'

I feel like I'm living in some kind of bizarro universe. Everything's all upside down. How is it possible that I discovered my new favorite song in an Old Navy ad? But Ingrid Michaelson's 'The Way I Am' reached out of my TV set and snapped my head around. Before I could stop myself, I'd rewound and played that ad 5 times in a row. I hope whoever picked this delicious little ditty got a big, fat raise.

'Presents,' Via Audio
From 2007's 'Say Something'

Via Audio are my new favorite cause. I want to help the whole world learn their name, learn their tunes and learn to love them the way I do. These kids think in terms of pop confections, creating tunes that just beg to be sung. Give them a listen and you'll pick up on hints of both of Montreal's whimsical pop tunesmithing and delivery akin to fellow IFLTS alums, Mates of State. The simplicity of their melodies is a beautiful thing to behold ... and catchy as hell.

Despite the downpour on a soggy beast of an August day, a multitude of die-hard Rufus Wainwright fans started lining up in the early afternoon to get the best spots at NYC's Central Park Summerstage. The weather didn't dampen Wainwright's spirit, though. The stylish singer-songwriter crooned his way through the glittering 'Release the Stars,' a heartbreaking rendition of 'The Art Teacher' and the let-me-try-that-one-more-time piano acrobatics of 'Tulsa.'

Watch Wainwright perform 'Release the Stars' and see more photos from the show after the jump.

'Writer's Block,' Just Jack
From 2007's 'Overtones'

Is it 'Spiderman''s MJ or 'Harold and Kumar''s Mary Jane you're flying high with, Jack? With insider references to bullet trains and Lois Lane, 'Writer's Block' is enough to make a stoner ComiCon buff's day. Sorry, Spidey, but in this debut issue from North Londoner Just Jack, the bass line is the real superhero. Funkier than Superman's trunks after a busy day saving the planet, the bass is the driving force behind the tune, and a surprising counterpoint to Jack's Cockney patter. With such a disco-driven core and his call-outs to comic culture, it's easy to overlook the fact that his ruminations on impending fame and the music biz are the real thrust of the song.

'Fraud in the '80s,' Mates of State
From 2006's 'Bring It Back'

Like an indie beach party, the bouncy hammond-esque organ and uber-hooky vocal melodies on 'Fraud in the '80s' make this one of the catchiest tunes I've heard in a million years, managing to evoke images of summer and convertibles even while it's sub-zero outside. Unlike more polished studio pop songsmiths (fellow endless summer enthusiasts, the Beach Boys, for instance), husband/wife duo Mates of State do little to hide or mask the idiosyncrasies in their voices, making the tune feel like an authentic conversation among friends. Several of the catchy little harmonies and vocal hooks have now fused with my brain cells, leaving me singing in the shower, humming while I bang away on my computer or walking home from the subway. Hell, they're even appearing as a refrain in the soundtrack to my dreams. The Mates were obviously right when they sang, "You will surely find this is pleasing to your ears."
