Other than the Mr. Belvedere theme song, the main song that's been stuck in my head recently is "Oh Lately It's So Quiet" by OK Go, because This American Life: 2010 used it to fine effect. More:

Why bother
It's gonna hurt me
It's gonna kill when you desert me
This happened to me twice before
It won't happen to me anymore

- "Why Bother?", Weezer (awesome 8-bit tribute/cover version from Weezer - The 8-bit Album). I know these lyrics sound resigned, but in the song, especially the I Fight Dragons cover, the sound feels energetic and kick-ass. I'm taking control. The next time I try this, it'll be on my terms.

Consider [the] possibility
That you've been had, but not by me

- "Just Apathy," Tally Hall. "Welcome to Tally Hall" is a more astounding song, lyrically, melodically, harmonically, but the singer sings this one line plaintively and playfully. It sticks with me.

You say they taught you how to read and write
Yeah, they taught you how to count
I say they taught you how to buy
and sell your own body by the pound
I think you like to be the simple boy
I think you love to play the clown
I think you are blind to the fact
that the hand you hold is the hand that holds you down

- "Everything to Everyone," Everclear. I've had this album for ten years? This song is arguably an argument about product differentiation in established multiline corporations. (But it's not.)
