I'll admit to some ignorance on this one for my part.  I don't often change notification sounds, or ringtones etc... my phone is usually silent.  Except for alarms.  With the new phone in hand I was setting it up and thought, maybe a new alarm would be better, maybe I'd gotten too used to its tones.  Something new might startle me to wake up better... It was then that I noticed the 'picker' or selection screen for it looked different than I had remembered.  Almost like it was disjointed from the rest of the aesthetic - to me at least, that's how I felt it looked.
