Instead of using DVD combo systems, many of us are now listening to mp3 and ipods, and
it is well. Why? Foremost because it is small and convenient, and you can bring
it anywhere you want.  But I think the
most important is that you can store thousands of songs inside one device, and
it is very convenient.  Most CDs can
store about a dozen songs, and although it is not really that much work to
change a CD, for most of us, it is a labor we would rather not do.  Just like the television set.  It is not really that much of a deal to go up
and change the channel, but now we all want to do using remote.  It is a small convenience, but something we
cannot do without.  For many of us,
changing a CD, and storing it back to the case is a little work which we find
irritating and frustrating.

Of course, if you have 
a lot of kids around the house, or you are a somewhat not very well
organized person, you tend to not return the CD to the case, and because of
that, it is not unusual to have CDs scratched badly, or even lost.

So it is great to buy the CD, and rip ( or transform it to
mp3 or wma files and store it on your computer, or your portable player).  However, you still do want to listen to it whether in the house or in the car, it is really better if you don’t
have to use headphones all the time ( be forwarned!  They say using   headphones excessively, and with a loud
noise may cause deafness!).

What’s the best thing to do? 
Well, if you have a DVD writer, you can copy all your mp3 files and burn
it to a DVD.  A DVD disc can store more
than 4 gigabytes of data, and based on the file size of mp3 music, that means
well over a thousand songs, or easily over 50 hours worth of music , or
equivalent of 50 CDs.  So if you get a
DVD player that can play also wma and mp3 music either in your car or in your
house, and you have a DVD burned, then that means it could well be days or
weeks before you even finish listening to one. 
Which means for every DVD that you burn, you get an equivalent selection
of songs that is even more extensive than what most mp3 players will hold.  After all, most DVD compo systems also will
give better sounds than most mp3 add-on players.
