|Pop n' music 5 featured a cleaner framerate, enhanced character graphics, and a new style/song selection interface.
Aside from the interface fix/change, konami also added quite a few new features to the game.
The most notable being the new EX song difficulty. New music wise, there's a whole slew on new available selections including a couple of songs from the previously "non-9 Button" Pop'n Stage dancing games. This new mix is pretty much what defines Pop'n for the next 4 mixes or so layout and character wise.
Pop'n Music, is aim for the young audience. The big foot panel of the DDR series were replaced is easy to press buttons.
This allowed kids a better chance of getting hits. They are game to suit different age/skill levels, on the beginner level the player only had to use a few buttons, the harder difficulty setting player had to use all the buttons.
Also the characters on the game are more child orientated as well as the music selection.
