For you I'd bleed myself dry

I woke up this morning with the song Yellow stuck in my head (Btw, the word in the gif should be look instead of see). Dont you ever wonder how a random song can suddenly pop in your head for no good reason? Or how you can easily play a song in your head while activating your brain cells for other purposes simultaneously?

This song is so beautiful in so many levels, in so many ways. I am glad that i rediscovered it today.
