MP3 problem

Hello. I have a little problem with the mp3's I am trying to play on my Meizu M6 SL.
I have about 900 mp3's on my player but only around 500 can be played.
I think it's because of the encoding that certain mp3's have.

Is there a tool, convertor, that could convert ALL my mp3's, that I want to put on my Meizu, to a readable format of mp3 that Meizu will understand?
I am tired of puting in mp3's that Meizu won't play.

Thanks in advance.

This thing is probably what you seek.

It can fix most problems on mp3 files that suffers things like bad vbr headers, frames, garbage, truncated files, whatever.
Keep in mind that sometimes it may eat up some of the tags, but that's the only bad thing. I really recommend it.

For encoding I think dbpoweramp is great.

The previous version I tried was pretty easy to use. It's not completely free though but it works.

The MP3 problem fixing didn't change anything.
So, I think I need to convert the files.

do the ones that don't play get displayed at all ? There is a maximum number of files limit which you might have exceeded. If so, try playing them with the file browser.
