How many songs make up a gigabyte?

Approximately 250 songs fit in a gigabyte, depending upon each song's individual file size. One four-minute song averages 4 megabytes.

Factors that affect song file size include the bit rate and length. Bit rate is the number of bits per second that are encoded in an MP3 file. This is similar to video resolution, which refers to the quality of an image. Like a higher-resolution video, the higher the bit rate of a music file, the higher the audio quality. Songs downloaded from the iTunes Store have a standard bit rate of 256 kbps. This bit rate provides good quality without requiring significant download time or more than 4 megabytes of storage space per song.
