When the first chords and "oh way ohwooohwoah" hit during the opening moments of the Season 2 finale of Chuck, I was hooked. It was one of those moments when both a show and a song are made better by the coupling.
"Now We Can See" by The Thermals is this odd mix of pop and garage rock (garage pop?) that sounds like music you shouldn't like, but you get completely sucked in. The songs all sound very similar, they're low-fi and grungy, but underneath it all are these pop hooks just trying to get out.
This is the song where they get out the most, and it makes the #9 spot on my list.
