Expandability

Expandability of memory capacity is a great option for an MP3 player

There are MP3 players out there that have a fixed storage capacity. On the other hand, there are also MP3 players that have a variable storage capacity. There are MP3 players that are expandable. There are MP3 players that come with a certain amount of memory and sometimes you can actually add more memory to it. Some MP3 players have memory cards which can be removed from the MP3 player. These memory cards can be replaced with larger capacity memory cards or can simply be switched with another memory card with another set of songs. You may have a one gigabyte memory card that you can use for hip hop songs and you can have another one gigabyte memory card that you can use for rock songs. Expandable memory is great especially for those who frequent the gym often and are usually in different moods when they workout.
