CD's? I remember those.

Salmo, you take all of your CD's and rip them onto your computer. Now, you copy them onto your iPod. Then, you take your iPod wherever you want to listen to it. Put headphones in it, plug the "mini" output (the headphone jack) into an auxilary port in your car, boombox, or home stereo. Now, you have ALL of your CD's everywhere and it weighs nothing.

I haven't actually bought a CD in probably 4 years now. I do, however, pay for a Rhapsody subcription. For about $10 a month, I can listen to whatever I want as much as I want. I DON'T own any of the music so if I ever stop paying, I lose access to it but, for me, it is a perfect solution. Kind of like having a $10/month jukebox with me all the time that will play anything I want. It streams and/or downloads over my 3G or wireless connection.
