Most people use MP3 players as a device for storing and playing audio music files. Personally, I like to use this device because of its simple and compact form, with high capacity to store songs and other digital data downloaded from internet. Some devices have also voice recorder for storing any kinds of speech, from lectures to interviews, from conversations to one’s own recorded ideas.
An MP3 player which has voice recorder function can be used in many other ways beside playing music. I often use it as a recorder for lectures that I have during my study. I usually sit in front of the class to be as close to my lecturer as possible. Because the main purpose of MP3 player is for playing music, the voice recorder function is usually not very good. However, it also depends on how lucky you are to get one good device. It is useful not only for recording lectures but also for an interview session where I need to pay more attention on several details. Believe me, it helps very much.
Talking to yourself is also a useful habit since it can help your brain develop broader horizon on one topic. Great ideas can easily pop from this activity, which is adequately documented. So, I recommend this device for you who like writing and composing some music.
