AX8600 Help Deleting please

So I got this phone two days ago and have successfully uploaded music to listen to, but setting songs as ringtones was hard.

I uploaded two songs through the "other_sounds" file on the SD card when I plugged it into the computer, put the card in the phone, moved the two files onto the phone in order to utilize them as ringers and now wish to delete them. Herein lies my problem. I cannot find the songs on the phone to delete them, there is no record of them, and yet they are still taking up space in the phones memory.
Is there any way to delete the internal memory of the phone, throught the service menu or something?

If anyone knows either how to delete them , or what is going on I would really appreciate the help...

Cheers in advance...
