MP3 Player

My son gave me an MP3 player for Christmas and I have been compiling my list of songs to download onto it. He is going to teach me how to do this as I am still a novice at much of our modern technology. The info that came with the player says it will hold 900 songs! It's such a little thing and it's hard for me to grasp the idea that all those songs will fit on there. I wish there was some way that I could just plug myself in and download a lot of technical information into my brain and then remember all of it! :) :)
