Fix : "Windows Media Player cannot burn some of the files"

So tonight I am in Windows Media Player and trying to burn a CD of fresh MP3 files I just made in Audacity.  Keep getting the error that some files can't be burned but no reason why is given.  Went into "more burn options" after unchecking "Burn CD without gaps" things worked ok.

Also, sometimes I have noticed simply trying to burn the CD again without changing anything will work.
