I bought one of these and after I received it determined that it would NOT play MP3s. There is a jack for an MP3 player as input, but no way to play MP3s as received.Now for you yung-uns...MP3 before the flash drive players ment a CD with MP3 files on it. This is a convenient way still to load music lists and play them in the home. Most DVD players will also play MP3 disks. So I wanted a clock radio to play them for those nights when I awake at 3 in the morning to worry about the world. An extended source of my favorite music would be the MP3 CD disk. It'll hold about 13 hours of music if you cram it full.So I regard this a misleading advertising by RCA Thomson and want ya'-all to know about it.
