well i cant even AA all song in DDR caus my PA isnt too good but i still like in the groove more caus songs are harder and they have extremely good song such as:
Destiny
Charlene
Delirium
Pandemon ...
Personnaly I find in the groove bether maybe caus the songs on ddr are getting old I havent played ddr extreme 2 yet but I dont think there is much new songs compare to in the groove ...
where i could download a DDR program to read the arrows and tune beacaus i downloaded some zip files with tunes but i dont have any program to read them i can listen to the song but there is no arrow
