This is my second mp3, the first one was sony but it didn't have the storage capacity that I was looking for so I got this one instead. I gave the sony one to my daughter so she could play with it. I have shown my mp3 player to my friends and everyone agrees that it is great. It is compatible with windows vista and you don't have to download anything, it automatically finds the program if you are connected to the internet and it is very easy to add music to it and pictures as well. You can also make playlists and if there are old songs that you want remove it is very easy to do so. My friends have asked me where they can buy it and I always tell them that I got it at Best Buy for 89.99. They come in different colors but I prefer red. So if you are looking for a great mp-3 with great sound, and storage capacity I would recommend you buying the YP-K3 and you will not need another mp3 player. And remember it store pictures that you can watch while you listen to music.
