Do you plan to play only audio tracks, or do you also wish to play video?

If you want to run your preferred music and videos in handheld gadgets such as iPhone, Zune, iPod, and a lot more, you need to have them formatted first into MP4.

That is to say, you are able to watch four films without charging again. Typical music tracks in MP3 format range in size from 4MB to 5MB.
Not only that, but they are incredibly cheap too.
