My Clip sometimes stalls while playing some MP3 files

Sometimes my Clip stalls while playing an MP3 file. Are there certain types of MP3 files the Clip is not 100% compatible with?

Any Windows tool which can convert MP3 files to another MP3 format which the Clip is compatible with fully? I don’t what the issue is exactly so I am just asking if someone had similar issues and knows what to do. 

Looking for a tool that works on Mp3 files in batch mode. I can’t do it manually on a single file one at a time.
