Voting Question: how can i put music from an mp3 player on my ps3?

the mp3 player is a sansa 1gb clip, and i downloaded the songs with limewire then put them on my mp3 with windows media player. i don't have a usb drive or anything else to put the songs onto my ps3, and i don't have money to buy one. my ps3 is a 250gb slim. when i connect the mp3 player to the ps3 with the usb cable and try to display all files or whatever it is, it says there are no files to display.
