Eric and I both have MP3 players. He uses his more than I use mine, even though mine’s almost completely full. I would like to use it in the car, but I don’t have a thing to connect it to the stereo. I was looking at the store to see if they had something like one of those cassette tape things that plug into your mp3 player and play the music through that, but didn’t find anything. I do have a 6 disc cd changer in the car, but I like a wide variety of music and changing cds isn’t really a smart move while driving. So, I found a cool website that sells a wide variety of MP3 player accessories for various types of MP3 players like iPod, Creative Zen, Dell, Zune, and Sansa. I have a Creative Zen, and my son has a Sansa. I found what I was looking for, and it’s a decent price, too. It also will fit both mine and my son’s MP3 player, so we can switch out sometimes.
