I can not beat it!!!haha man its sooo hard,its like the through the fire and flames of rockband :P.Im so close to beating the game on expert guitar too,I need 2 more songs on the last tier and cant beat them,this song and flirtin with disaster.these i have been stuck on for almost a week now :'(.i really suck at scaling up and down the fret buttons.i dont use the bottom 5 frets,havnt got use to them so i just forget them.
