Caillat develops a smart and uncomplicated sound in the upbeat, sunny-day song. Background vocal lines weave across auxiliary percussion beats as Caillat's lead lines carry the tune through three breathless minutes, with only the briefest of pauses.
The song, as its title suggests, is about marriage, and plunging in cold feet and all: "Cause every time before it's been like / Maybe yes and maybe no / I won't live without it, I won't let it go / Whoa, what can I get myself into?"
Caillat knows about commitment. She's made tremendous strides since first trying to break into the business as a timid 'American Idol' hopeful, where she auditioned twice and both times was sent packing (the first time she was so terrified she couldn't sing). She turned to her MySpace profile to launch her career, and in her output leading up to and including 'I Do,' her sound has become increasingly more confident and focused.
'All For You' will be Caillat's third studio record, and will feature special guests, including Common. There are also rumors of a collaboration with the country group Lady Antebellum.
Caillat has worked well with guests in the past -- she contributed background vocals and songwriting to Taylor Swift's single 'Breathe,' as well Jason Mraz's song 'Lucky.' However, Mraz's tune beat Swift's track at the 2010 Grammys in the Best Pop Collaboration with Vocals category.
