Query: UNhappy

I've always been told to say something nice about someone or something if you have criticisms. So, the sound from this system is good. BUT - - - it doesn't go from CD to CD, has no mute button, and is very slow responding to the remote.The next CD player we buy will only do CD's and not DVD's as well. I want something that works well with the functions I need, without extras that I don't need - - - but that seem to interfere with its basic functions!We've had the system for a year now and, you've guessed it, are UNhappy. (I'll be sure to check out the reviews before my next purchase.)
