Why does my iPhone start playing music randomly?

I haven't dropped my phone or anything in case you're wondering. It's completely fine, the music plays well and everything. I keep my earbuds in it to make sure if it rings in class or starts playing music I won't get suspended… Anyway, sometimes I put them on to find music playing. When I go to the music app it says that I'm already on my 112th song already (that's an example #)! This has happened a bunch of times and I don't know why. I've already considered that something in backpack or me moving around causes it to turn on by using the shortcut or something but are there any other possibilities and how can I fix them?

Can't find iPhone 4 Verizon MEID/ESN?

My friend broke his verizon 8gb iphone 4, so he gave it to me and he got a new one and transferred his number. I finally got the iphone up and running, but it says searching under where the signal bars should be. When i go to settings>about, there isn't an MEID or ESN #. Its strange because that's where it should be. Also when i connect it to itunes it doesn't show the phone number or meid. Any ideas what is the problem here, or how i can find the esn?
