if im not mistaken that model should play mp3 files without any problem, if not then consult the docomo user guide.
I have the same problem! :/ I'm using a Docomo phone in California USA and was wondering how can put music so the phone will actually read the music files in music player. I can get the songs to play in i-Motion>Micro SD>Multimidea, but I want the music player so i have more features! I have tried every file created by the phone inside the Micro SD card and I can't get the Music Player to read my songs! I have converted them to 3gp/mp4/wma and changed the file names and STILL nothing! Help anybody??
This was posted somewhere else on the forum. Use this utility to help you format your sdcard based on your model (whether it is nec, sharp, panasonic etc.) and then when you drag stuff into this utility window, it will put them in the right places.
EDIT: Ok, looks like I was mistaken. This doesn't transfer music files. But would be useful in creating the files required when transferring ringtones, images, videos etc.
To copy music you need to create those folder on your SDcard. PRIVATE/<Model type>/MUSIC and then paste them into that file.
An example like in my case: PRIVATE/CASIO/MUSIC.
