I’m completely dumb when it comes to this, so let’s start from the start. What do I…
a) need
b) do
Thanks 
Btw, it’s for a ps2 ;D
A) you only need the game and you have to go to GHero Tunes and you can dowload songs
B) go to music studio and make music buy playing on your controller. you can adjust the pitch of the note. ITS REALLY HARD! I suggest donwloading songs.
C) To get internet you need a broadband cable ; ) good luck!!!
