Down loading songs
RCA's website has the software/manual that you need if you lost the CD
Use Windows Media Player to transfer music and delete songs
As far as downloading songs, you can sign up for a wide number of music services - each one has a different download method, and the company website will explain how to use it. The problem with this RCA player is that it was tied to Yahoo!'s Musicmatch Jukebox svc, which was cancelled in October 2007, so you will have to find another music service. Some music services will recognize the RCA player directly, and you can use their svc to download the songs directly to your player. Other services you will have to download the songs first, and then transfer them to the RCA using Windows Media Player afterwards.
