Music on LG Xenon gr500fd

Hello i got my LG xenon gr500fd 2 days ago, and i put some music in it. and it updated right away now i put some more music and it will not update. i just only see the old music in the music player. but if i take out the SD card and insert it in a adapter to a computer i see the music that i added. how do i get the phone to recognize the music?

They are Mp3 format sound and the average sizes are 5mb.

@Moment4Life:
Strange, for whatever reason they are a format the Xenon doesn't like.

Can you try re-encoding one to MP3 using MediaCoder or similar tool?


@Spice:
The Xenon auto-categorizes audio files, regardless of where they are stored.
If it is 300 KB or less, it is considered a ringtone
If it is over 300 KB, it is considered an audio file
However, on non-AT&T Xenons, the firmware prevents you from assigning external ringtones unless they are received over-the-air (send a MMS to yourself or receive via Bluetooth).
