Why is track not compatile with iPod?

You cannot use iTunes or Music to copy directly from CD to an iPod. Tracks must be imported into the library, then synced or manually added to a device. What format, bit and sample rate have you used for the import? Tracks that might play in the library may not necessarily be compatible with your devices.

Does it play properly in iTunes? You might be able to convert it to a new copy that will sync. You could also see Repair security permissions for iTunes for Windows - Apple Community just in case it is a weird permissions issue. Otherwise yes, you may need to re-rip the original disc.
