Why won't my itunes sync with my media player?

So I have a iphone 4 and when I 1st downloaded Itunes all my songs from my Media player synced with it and it let me put all my music on my phone but I recently added some new songs (63) to my Media player but they did not show up in my Itunes so now I have no idea how to put them on my phone.

Also my Media player won't sync with my phone too.

ITunes and media player have different program so I think it would only would work if you burn the songs in a cd and then import it on iTunes and put it in your phone

  • Moving from Windows Media Player to iTunes? I have a folder on my PC called Films. I wish to move this to my iPhone. I tried dragging - does not work. Any other ideas. Please be clear.
  • IPhone/Windows Media Player? Basically what's happened is that WMP says please connect a device even though on my iPhone says it is charging which means it must be plugged into the laptop! How would I get past this and send a video or sound track to my iPhone! Even a suggestion would be great!
