Similar to other audio formats, the Internet is a good source for mp3 files. There are millions of music websites wherein users can search and download the mp3 format of the songs which they want to listen to and subsequently keep in their computers or portable players. Some of these sites require users to pay a certain amount before they can acquire mp3 music downloads, while others allow their visitors to get mp3’s for free. The length of time in downloading an mp3 from these websites partly relies on the Internet speed of the computer which is receiving the file. Greater Internet speed naturally results to less download time. With regard to file size, mp3 downloads can be as small as 2 megabytes and can go up to as big as 15 megabytes or more, depending on the length of the song and its quality. An mp3 that exceeds the six minute mark and has a high sound quality generally has a larger size than other files.
