There are some songs that are really really catchy that stick with you the whole day, but you love it. This is one of those songs: "Your Beauty is a Knife I Turn On My Throat" by Eagle*Seagull. I highly reccommend this power piano infused track. If you want to learn more about this band, I think you will get much more out of their website than me. All I know is that this song is good and you should listen to it.
