Can't burn newly created playlist to CD with iTunes 12.1 I just want to burn some music for my Mom to a CD-R.  I've done this multiple times. If I check MP3 CD box, I receive message stating all music is not MP3, and it won't allow. If I check other option, Data CD or DVD, it copies but if I insert into CD player, message is, " No Audio." 

This can't be this hard.

Any help is appreciated.

I have OS 10.7.5

Thanks
If you go to View Options and selected Kind, you'll be able to see which of the tracks isn't an MP3. You can then convert it/them to MP3 and replace the originals in your playlist with the new ones.
