if you're asking how to get songs onto the player, then most players come with software that allow to put songs on the player through a USB or IEEE 1394(firewire) connection.
if you're asking how to get songs, you can buy cd's and rip them to your computer, subsribe to a music service like Napster-to-Go, or other stuff.
hope this helps
