Samsung SGH-E730

I know this sounds stupid, I bought this phone yesterday.. it came with the USB cable and a software.. i installed the software as well as the samsung usb driver.. however, while im using PIM & FILE manager software, there is a menu called "melody to phone" .. but it won't let me click it once the phone is connected.. so I just want to know.. is there ANYWAY to upload mp3's on this phone?!?! PLEASE LET SOMEBODY LET ME KNOW AS SOON AS POSSIBLE!! THANKS
