Problems with iPhone Result of Bad Music???

Question

In the last few weeks I've been experiencing problems with my iPhone. I did a lot of research online, and figured that it is NOT this "dead strip" that others have been having problems with; however, 75% of the time, the slide bar will not respond for the first 7-8 times I try and answer a call or turn off an alarm.
As time went on, the problem got more frequent and more involved. The phone might work fine all day, but as soon as someone tried to call, it starting going nuts, even after the call was over. None of the applications would respond to my touch and in the rare case that they opened, they would run incredibly slow and crash. The phone would freeze and need to be restarted. In the more recent days, during the restart, in which the only buttons I'm holding are the sleep/wake and home, my music would spontaneously start playing, starting alphabetically with the first artist on my list with no controls for me to stop it.
Most of the time, after a restart, the phone would continue to work fine, until a call comes in and starts the process all over...
After failing an attempt to fix the problems by deleting many songs and videos to clear up some room on the hard drive, I decided to restore my iPhone, as I have done once before, but this time not syncing with previously backed up data. I allowed iTunes to erase all the contents of my phone and then manually put most things back on. Since then, the phone has been working flawlessly. However, there is one problem remaining...I have not put any of my music back on the phone.
And now I am afraid to!! Even though all that same music has been on my phone for 3 months, and only now have I begun to experience problems, is it possible that the iPhone operating system is more fragile and more vulnerable to bad files that might otherwise work fine on my computer? I have no viruses on my computer, and I have never installed any of these problematic third party applications on my phone. And if it's not the music, what else could be causing these problems???

This is exactly what apple care is for. Why delay and torture yourself when you can take it in and either have it fixed or have it replaced?
Take it in to Apple
