Songs won't play on iPhone but will in iTunes...why?

Newly Purchased songs on my iPhone won't play?

• Okay, i have a lot of problems with my iPhone. it's a 4S, and up until a month ago it had been working fine. But now I'm freaking out. I never plug my phone into the laptop containing my iTunes library because it has some sort of virus. iTunes works fine, but the internet is messed up. Anyway, i wanted to download a CD, so i plugged my phone in, downloaded the music and unplugged it. I listened to my phone the next day, and every time a song that I purchased, all the way back at Christmas, skips over and won't play. it says I have the song but when i play it it skips to the next song. Everything plays fine on my library, but when I plug my iPhone in and look at what music it has, the songs that won't play are sort of whited out, and they have the little spinning arrows that mean "sync" next to them. They won't play on my phone. Yesterday what I did was delete them off my phone and then put them back on. But now when i go to my phone (under iTunes devices) and look at the music, click a song and hit delete, it does nothing. It won't delete anything off my phone. Even the songs that work won't come off. Someone please help me! :(

• Answer:

  I would recommend you to report that problem to the device/mechanical service... They are the right people to go for.... Good luck!
