You can be addicted to much more than just drugs or bad habit. Sometimes you can be addicted to love. Danish singer Juanna recently put out an EP titled 'Addiction,' with the stand out track, "Roller Coaster." Juanna sings about a relationship that takes her up and down, without much security guaranteed. The beat has a driving marching band rhythm that is reminiscent of Coldplay. But just like a roller coaster, it also switches up and lightens up for a moment before the drop. You must be this emotionally tough to listen to this one.
