An MP3’s file quality varies based on the bit rate that was originally used for compression with bit rates of 128 kbps, 160 kbps, and 192 kbps being the most common.

MP3 files are extremely common and are supported by almost all portable music players including the Apple iPod and Microsoft’s Zune.
