How to transfer metadata to the mp3 file title?

Hi. I have all my MP3 files tagged by MP3tag on my pc, and no trouble whatsoever. But I copied all my files over to a microSD card to my android phone. The music app that I use to play them is called 'Cross DJ'. It works fine, but it does not read the metadata: rating, year, genre etc. I had the amazing idea of getting MP3tag to rename the MP3 files on my android with selected metadata in the title. But I don't know how to script for that: in fact I know nothing about making my own scripts up. If that is even the right expression. I can't access MP3tag when I have my android connected to my pc when I click on the context menu, so I guess I would have to do the conversion first on the PC, and then transfer the files over. Any help greatly appreciated.
Thanx for reading
