Rock Band Virgin

So I know I am behind the times but I played Rock Band for the first time this weekend.  I started on bass.  My game play began at awful and rose to mediocre.  I switched to lead vocals and did pretty well.  Mainly because I knew most of the songs that we were playing.  The songs we did best were Black Hole Sun, Creep, (Wanted) Dead or Alive and Say It Ain’t So.  Is this a game for people who love rock music but never learned to play an instrument or a fun outlet people who know how to play already?  That game is really fun and I can see how it can be addictive too.  World Tour 08!
