Addictive straight up addictive. Had this for almost a year and never played. I mist out a whole year and could have been in better shape. I use this to get a little exercise. Couldnt recomend enough for those who like to challenge your self. in a week im already on expert for a few songs, rest is hard and most of those I put on a faster pace seems how I cant do expert yet on them. Enjoy everyone.
