Obviously, my stereo plays tapes. But there's only one in the whole house. So if I want to listen, I have to listen there. That's inconvenient. I got a discman in my room that plays cd's on a pair of computer speakers. I have other cd players scattered about the house. The bulk of my music listening is done in front of the computer, off of mp3's. In my radio there is no tape player. Too old. So....basically, there's very little access to tapes!
It's pretty clear that cd's have supplanted tapes as a music transfer medium. Yet, cd's still have some drawbacks. They are not easily writable. You need to have special equipment to write to a cd. Those are however becoming much more common than before. Many computers come standard with such a thing. What else? There aren't many more disadvantages to cd's. Sometimes it might be said that the sound is too sterile. But that's a complaint levelled by those who still listen to LP's. And those are so far out of date that it's not even really worth mentioning. Cd's are definitely cool.
Can I count mp3's as cds? I guess not. Even though they are easily transferable back and forth. So maybe. You can get mp3 players that can hold over 6 gigs of data. How many songs is that? Let's see. Average of four megabytes per song. That makes the mp3 player capable of holding 1500 songs. an astonishing amount. Staggering, really. Huh. Anyways. Who the hell wants to have tapes when you can have 1500 songs at your fingertips?
