Samsung Music MP3 not playing

MP3will not play.
AAC format will play
Flac will play, but from a CD you get a lot of horrible skipping!
The ridiculous part is the goddam thing records in mp4, but won't play mp3, and recognizes jpg's, so there must be some politics going on here. There is no such thing as a "lossless" format, I think they want you to re-buy everything as usual.
