My music on my iPhone got messed up after ios 6?

Okay, so I have an iPhone 4S, and I updated my phone to ios 6 while ago. Ever since then, my music has been messed up. On albums, it appears that it doesn't have an album photo, but when I play those songs, they do have a photo. Also, there's a few songs that I deleted after purchasing it that's not fully downloaded. It won't let me delete it from my iPhone, and it doesn't sync into my iTunes, so I can't delete it like that either. What can I do?

Current value of iPhone 4/4s?

I have a black 16gb iPhone 4 used that is still in functioning condition, no cracks, minimal scratches, and a two small scuffs. The back had a screen protector on since the beginning and is new when peeled. Original box with accessories and manuals included.

I also have a white 16gb iPhone 4s that has never been used, all the accessories are sealed (except headphones), with the original box still in shrink wrap.
Both phones are for at&t.
Would love to get an estimate, thanks!

Is this the worst creationist argument ever?

"A Christian finds an iPhone laying on the ground: Oh, someone must have dropped this!
