Nowadays, when listening to music, we can’t not to talk about MP3, MP4 or MP5 player.
20 years ago, many music albums were still released in cassette format. Cassette albums began to disappear in the market with the introduction of CD, DVD and other digital recording format such as digital audio tape and MiniDisc.
Since Oct 2001, Apple introduced the iPod portable music player and has changed the way we get our favorite music.
Now, we are buying digital music from the net and download into the MP3/MP4/MP5 player or our mobile phone.
The cassette player in the background is old Walkman and my wife use her LG Shine mobile phone to enjoy her music.
