The only reason why I somewhat dislike the game is because it has ruined a lot of songs for people who aren't musically inclined. The songs that only true "music fans" knew and listened to have now been heard by everyone who has ever played the game.

Also, I hate it when people think that just because they can play expert on guitar hero, they can now learn how to play real guitar.

But...other than that, I enjoy playing the game and it has kept me entertained for hours at a time late at night chillin' with the guys.
