MP3 vs MP4

[MariaJane]

Most people say that MP4 is better. But I need more suggestions if I should use an MP3 or MP4 for my music collection. Which one do you have? MP3 or MP4? Why do you choose to have that one?

I suggest you buy MP4. It has more features than MP3. MP4 can play and store audio and video files. It has a large memory storage, better sound quality, a small screen for watching videos. MP4 can offer an even greater range of features such as email, web browsing, instant messaging, music and video download, digital camera, bluetooth wireless technology and many more. It's worth buying MP4.
