Cannot edit ID3v2Tags - Example doesn't work #154

Hi

The example shown in the README of the repo for Setting ID3v2Tags doesn't work. I'm trying to editing some fields but unless you remove the previous ID3v2Tag (call removeID3vTag) from the mp3 file and set a new one, the changes doesn't take effect and the outputed mp3 is the same as the original.

But If I remove the tag to save my changes, I lose the previous data when I only want to update some data. The only workaround that I found to this is to copy manually all the previous fields in the new tag and then update it. For only update one or two fields, I have to copy ALL the rest to maintain all the previous information, what it shouldn't be necessary

I tried it with latest version of Java 8

Thank you

Don't copy it manually, copy the whole tag (tagOfYourVersion tag = mp3file.getID3v2Tag() ), than call the remove functions, edit your tag and reattach it.
