Query: MP3 Problems

I bought the power box because of the mp3 capability but every cd with mp3s that I put in skipped songs, or would not recognize songs on the cd. I would use new cds and that did not help either. The sound is very highs oriented with no bass at all. The GFI is a nice feature but what I really want is a work radio that functions as a radio and can last a little. When out of the box there are malfunctions with the MP3 capability there is a problem. So I turn on the radio to find that there is no reception. Very bad very bad!!!!
