Try downloading the trial version of another burning software and see if that one can burn songs. Also, the song in your screenshot is a commercial one. Try burning one made from scratch by yourself and see if it does make a difference.

Also all joking aside you can actually try uninstalling Windows Media Player. It does monitor these things and I guess something could have messed it up.

So basically try these steps:

1: Try burning your own song. Does it work?
2: Uninstall WMA and try the song again. Does it work?
3: Download a trial software and try again. Does it work?

Also, and this may be the more important part, go in your control pannel and check for the Icon called "Nero Burn Rights". Open it. make sure everyone has burn right, that the little checkbox down the window is checked, then click re-initialize burn rights.
