Just curious... Im currently on vacation on with my Macbook.
But been busy creating new ringtone files for my iPhone
..
These extentions are .M4R...
**Does Mp3Tag support this tag?**
If not will it in the future (i hate iTunes, prefer to edit all tags manually with mp3tag)

I'm not 100% sure, but my guess is that they are just .M4a files but renamed as .m4r. But what I understand is that Apple Ringtones are time limited (I mean not able to be a complete song, but just an excerpt of that song).
Found something about time limits for ringtones.

And another something on .M4R

I was just curious... Because last time I synced a tone I downloaded it appeared on my device with some weird chinese characters.. but the file name was (for example) " **Ringtone\_2.m4r**"
So somewhere in the file must be additional tag/information
Im creating Lots of ringtones from (mostly from Instrumentals) and I don't want to be guessing which ring tone was which when its time to select a ringtone.
