MP3 is a popular compressed digital music format that allows consumers to store many songs on a very small device called the mp3 player (or digital audio players). This compressed music can be purchased over the Internet or created by the consumer using common computer software with their personal CD collection. In General, consumers need to use a computer program to convert a CD to mp3 format, and then move the converted files to the mp3 players for listening.
Consumers can also purchase music over the Internet. This will require a computer, an Internet connection and an account with Internet music provider in order to purchase the music. Once the desired music is purchased it will be transmitted through the Internet connection and stored on the computer hard drive. Every song you purchase comes with a unique ID/key. Without this ID the song cannot be played.
This ID/Key is transmitted to your computer via the Internet when you first play the song on the computer. This ID/Key is stored on your hard drive automatically.
The Mp3 file can also store the song title, the artist, type of music, etc. This information can be displayed on the screen of the mp3 player. Mp3 players on the market today their memory capacity, range from 128Megabyte to 80Gigabyte. In computer science a byte is a unit of measurement of information storage, most often consisting of eight bits.
1 Megabyte=1,024 kilobyte where 1 kilobyte = 1,024 byte, and 1 Gigabyte = 1024 Megabyte.
Typically a 4-minutes song takes up 4-Megabyte of memory space on the mp3 player based on a common compression ratio of 128kbps (kilobits per second). 1byte = 8 bits.

About mp3 and music formats:
What is MP3?
MPEG-1* Audio Layer 3, more commonly referred to as MP3, is a popular digital audio encoding format. It uses a compression method that is designed to greatly reduce the amount of data required to represent the audio recording, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners.
Music is ripped from a CD into WAV files then a process converts these files into MP3 files which are 1/10 of the size of the WAV files.
*MPEG-1 defines a group of Audio and Video (AV) coding and compression standards agreed upon by MPEG (Moving Picture Experts Group).
**WAV is a standard file format for digital audio
Mp3 vs. WMA vs. WAV
When music tracks are ripped* from CD they are converted to WAV file first; usually for a 3 minute song it is about 30 Mega-byte. The MP3 Codec (Coding/compressing – Decoding/Decompressing engine) converts the WAV file to MP3 format and it offers near CD quality sound at one-tenth of the file size. It is not common for listeners to be able to distinguish the difference in sound quality. MP3 file or WAV file can be converted to WMA (Windows Media Audio) file where it is almost half of the mp3 file size, but has a lower audio quality.
*Ripping (also referred to as digital audio extraction) is the process of copying the audio data from one media form, such as CD, to a computer hard disk drive. To conserve storage space, the copied data is usually encoded in a compressed format such as MP3, WMA for audio.

What is ID3 tag?
ID3 tags store information about MP3/WMA files. Common information used in ID3 tags are: Artist, album, genre, year, track number, track title, etc.
ID3v2 tags have additional fields to accommodate Web site information, lyrics, equalizer presets, pictures/album arts, etc. For both ID3 tag versions all fields are stored within the music files.
These ID3 tags can be edited. ID3 tag information is not normally stored on the CD content so you might have to get this information from the internet. This can be done using the “Find Album info” from the Windows Media Player 10 (WMP 10) or manually by typing in this information from the album cover of the CD. Right click on the mouse to show the selection within WMP10.
