There's a version of Death Cab for Cutie's Passenger Seat that needs to be on every mix you make for a potential mate. The song itself is amazing, it's relatable, it's beautiful, and it resonates with you immediately. The lyrics are simple yet sweet and in this particular version (see below) is one of the most beautiful versions of the song I've ever heard.
It's hard for me to listen to now without thinking about my first love -- or any love for that matter -- and how it felt to sit next to them in silence. To look in their eyes and feel completely connected. It's such a beautiful feeling and it's hard to explain so I'll just let the song speak for itself. It'd be best to listen to the song with headphones on and let the sound of Ben Gibbard's voice bring you to tears.
When you feel embarrassed then I'll be your pride. When you need directions then I'll be the guide. For all time.
