My music won't transfer to my iPhone?

I got a new CD, and transferred the tracks to my iTunes library. However, whenever I try to transfer them to my iPhone, it shows a red circle with a diagonal line through it, and won't let me transfer it? Please help if you can. Thank you!

Also, if you know about how to delete music that is grayed out on my iPhone, look at my most recent question.

Tipard iPhone transfer is the leading software of iPhone which helps Apple users transfer their Apple devices (like iPhone) data from PC or files from PC to Apple devices(iPhone, iPad, iPod)
