Some other commonly used encoding rates are 160 or 192kbps.
LITHIUM-POLYMER BATTERY (LI-POLY) —A battery composed of
lithium, a light metal with high electrochemical potential. Lithium
batteries are light and store high amounts of electrical energy. Because of
this, lithium-polymer batteries are ideal for your portable device. Lithium-
polymer batteries do not use poisonous metals, such as lead, mercury, or
cadmium, and have no "memory effect" problems (caused by not being
fully discharged before a new recharge, and remembering a shorter
battery cycle). However, they are more expensive than conventional
nickel-cadmium (NiCad) and nickel metalhydride (NiMH) batteries.

MEGABYTE (MB) —About 1 million bytes. Bytes, megabytes, and
gigabytes are measures of how much data a storage device can hold.
Forexample, a 3-minute MP3 encoded at standard bitrates is
approximately 3 MB in size.
MP3 —A member of the MPEG compression family, MP3 is a
commonly used compressed digital-audio format. MP3 encoding
transforms digital audio files (like WAV) to provide reasonable audio
quality in relatively small file sizes.
PLAYSFORSURE—Digital Rights Managed music in WMA format (See
reference to Digital Rights Management above).
SHUFFLE —A Play mode that randomly plays tracks once only from the
