not really
by any chance does your player look like this?

if it does .... download
swift sound

and use it to recode the files .... sorry but it's that .... or delete the files
That player (and all the re badged variants) has a problem reading some MP3 files.
(variable bitrate MP3s tagged with track details)
there is also a problem with copying files on some cheaper players .... the best "fix" is to connect via USB .... and drag and drop the files over into the player
(copy paste will generate errors)
at that point my knowledge expires .....
