My IPhone won't play certain songs?

I just updated my iPhone and all my non-iTunes songs won't sync. Every song that I have bought from the Itunes store sync fine, but ones that I got from CDs and stuff won't sync. Originally they'd show up on my IPhone but would have the red stop sign thing inside a circle and would be skipped over. I couldnt play them no matter what I tried. I have even put the songs into separate playlists and tried installing that playlist but still dosnt work.

That is weird

  • Why won't songs play good on my iPhone 5 but play normal on iTunes? When I download music and import it to iTunes, They play fine and normal but as soon as i put them on my iPhone they sound scratchy or like if they were getting fast forwarded. I don't think it's my iPhone because I've put songs in it before but this just started happening today. What's the problem, How do i fix this?
  • Why won't my iPhone play certain CD's? I've got tons of CD's left over from before I ever got a iPod or the like and usually, once moved over to iTunes, they play fine on any device. After the most recent update all of my albums that I have a physical copy for refuse to play and my phone keeps prompting me to put in passwords as if I'm trying to make a purchase. It's getting fairly annoying and I'd enjoy assistance on this topic.
  • Why won't iTunes let me put certain songs onto my iPhone? ITunes used to work fine until recently. Now there are certain songs or artists that won't drag and drop onto my iPhone. Any answers?
  • Why won't Facebook let me move certain photos to certain albums? I want to move certain photos to certain albums and when I click on "edit album" then i hit this arrow button on the picture and when i hit "move to another album" it gave me an option of 2-3 albums to put the picture into. What should I do? The picture i have in the album was from my iPhone that i currently don't have anymore and that's the last picture of it! Please help me! I don't wanna erase the album or any other!
