We all have songs we love and come back to every now and then. Too bad for them, because this thread ain't about 'em! This thread is about those songs that either bring you to a happy place, always make you sad, or have a special place in your heart. You may even use one during your first dance with your husband/wife at your wedding.
Secondhand Serenade - Fall for You
I never liked emo music, and I still don't, but this was playing when a girl and I were in a car at the height of our "relationship." She had me sing this song to her every night before she slept and would refuse to sleep, if I didn't. It could be 5 am, and she'd call me up, anyway, and ask me to sing to her. The song was also representative of our situation at the time.
Pink Floyd - Comfortably Numb
Aside from being an absolutely phenomenal song, that talks about how life can be tough and tiring, but you just have to power through. This is especially true, when you're trying to keep a dream alive.
Edit: Changed the title from "Movies that have meaning" to "Songs that have meaning." ><
Edit 2: Oh damn, never mind. Can a mod change that por favor?
