МРЗ ОК!

 My parents bought an MP3 player for B4______________ when I graduated from college.  I have to admit that, when   I first B5_____________ it,  I wondered what I was going to do with it. Now, however, I use my MP3 so much,          

I don't know what I B6_____________without it.

       I've stored my entire CD collection on the player and it's still less than half full. I have it B7__________________   to the stereo system in my car. It is very convenient to have all my music at my fingertips.

       I use my computer to copy songs from my CDs. If it's connected to the Internet, it automatically categorises information about the music, album and artist. When I want to listen to a certain artist I have all of their albums ready play. If I want to listen to a certain kind of music, I can just select that music and the player plays any music categorised as jazz, rock, or whatever other categories I have.

       There is also a play-list feature on the player that B8__________________ you to make play- lists for when you're on the move. Once you put your music on the player, you can access all the features without B9________ it to a computer. You only need a computer to put the music on the player in the first place.

The only thing that I don't really like about the player is that it's sometimes hard to remember everything that I B10 ______________ on it. The list of albums is so long that I often forget that I even have a CD player!
