How popular are multiple disc CD changers? It seems that they would have been replaced by all of the available MP3 player setups or just MP3 CDs for that matter. Both of which can hold the content of numerous CDs in one place. Though now I assume that you can load a CD disc changer with MP3 CDs and have a huge collection of music in the CD changer. A CD changer does offer the convenience of not having to change a CD while driving, but then again so do the MP3 player options.

This video shows the basic hookup of a CD changer in a BMW 5 series. This car is already wired for a CD changer, so the set up work was already done for this installer.

Have CD’s gone into obscurity yet? You always hear about how CD sales are way down in stores, because all of the sales have moved to digital music vendors. So I was thinking about how much longer do music CD’s have before they become the next cassette tape or record. Though records still maintain a vinyl following. And if the CD is to be replaced, what will it be replaced with? Will it all just be digital online. Will they try to sell albums on some copy protected flash drive?

I still like to have something tangible myself. If your computer goes down and your hard drive gets wiped out, there went all your music. The same event can happen with the iPod or whatever MP3 player you use. With a CD you still have the music to reload onto your device.

Though I understand why digital music is so popular. Why pay $15 for a new CD when there are only one or two good songs on there. When you could just buy those few songs you want for a buck a piece on Itunes, Amazon, or even the Wal-mart website. And I am sure it greatly reduces all the clutter of having to store all of your CDs in racks and trays.

We will all just have to wait and see what comes of this technology.
