Oh what a change! That's called a quick turn about. And that's the beauty of it. Music shakes you up. Don't expect to remain in the same frame of mind. Its not possible. Unless you're dead. Or at least dead to music (I personally haven't found anyone of that nature).
Its beautiful. Music can alleviate your mind or depress your brain. Any beat, any sound, any tune, any word can disrupt your mental zone. From a happy disposition you can turn into a love-sick puppy. It's the feel you associate to that music. The upbeat music could have a different effect on you. Everyones relation to music varies. And that's the true joy of it. Music is supposed to entice and excite your senses, in whichever direction it deems fit.
