Ok so I just updated for the first time since I got it, I got like 200 updates and music was one of them so I go to try it out on my playlist but it only plays 2-3 songs o. Shuffle and stops and the play button stays on play ( when it displays the pause button) but if it's off shuffle it plays them all and just to add the playlist has 23 songs. How can I fix this and I have to press the home button hard for it to go to the home menu from any app it's not how it used to it was a hair trigger thing not its like push hard and hold. How can I trouble shoot or should I get it replaced thru the warranty it covers accidental damage but that means backing it up, and speaking of backing up when I updated it erased everything and when I got everything back some music vids don't work and I bought them on iTunes it says URL could not be found???
