A 4 gigabyte MP3 player can hold approximately 1,000 songs. This estimation assumes that the songs average 3 minutes and 30 seconds and are encoded in MP3 format at 128 Kbps.
The number of songs that can fit on a 4 gigabyte MP3 player varies based on the length of songs, file type, format and encoding method. MP3 players can store songs even if they are not encoded in the MP3 file format. For example, songs encoded in the FLAC or OGG file format are higher quality than the MP3 format. These formats take up more hard drive space, which means fewer songs in those formats fit on the MP3 player.
