There's a whole slew of songs that I'm currently addicted to:
"Sweet Disposition" - The Temper Trap
"Your Song" - Kate Walsh
"Your Love" - Faye Wolf (cover of The Outfields "Use Your Love")
"Rescue Song" - Mr. Little Jeans
"Stutter" - Yuck
Pretty much anything by Yuck
"You" - The Pretty Reckless
"Young Blood" - The Naked and Famous
That's all that comes to mind but I know there's way more than that.
