What is an MP4 or MP5 player ?

I have heard and read about MP2 and MP3 conpression standards and understand them for the most part.

Now what exactly is MP4 and MP5? Does it exist and do something, or is it a mere marketing thing?

MP4 is a video format, so players such as the Archos Gmini's are MP4 Players, MP5 is a machine gun. :D

Where did you hear about MP5 players?

So MP4 doesn't do anything for music, correct?

MP5 - Beijing tourist markets - did't buy since it sounded wrong.

Well, MPEG4 compresses both audio and video, the audio format being AAC, but when referring to MP4, it is video.
