What is a good MP3 player/recorder that I can use to download the files to a thumb drive to use in my HK system in my new Ram 1500 Longhorn. I have never used MP3 but I have a ton of CD's that I would love to download so that I can enjoy them in my truck. I presently have my Iphone and Sirrius radio but really would lke a better source. Thanks in advance for your recommendations and advice.
