Any way to get full MP3's onto phone?

Is there any way to get full length and quality mp3's onto ones verizon phone. I just got a Samsung Sch-u740 and would like to put a few of my favorite songs that I already own onto the phone, without buying them again from verizon.
Is there any way to do this via the internet or a usb data cable? Keep in mind I mean full length songs not the ring tones with size limitations like mentioned in all the stickies.

i have a lg vx8300 with a 512mb micro sd card.. i have about 150 full length mp3 songs on it. it's pretty simple to copy them over. i just use the card adapter and plug into the card reader of my computer.

if you don't have a sd card, try to use your phone's memory to check if you phone is able to play mp3.. use bitpim to copy your mp3s to your phone using either a usb cable or bluetooth connection.
