Great game, been playing for a few days now--but I notice there is no practice mode for guitar, where the player can learn the song being played at a slower pace. That's really too bad. There was a practice mode for guitar in earlier releases of Rock Band; I would start slow and work my way up. Now I must learn to play the guitar parts in Hard or Expert mode at full speed. I can see why this was left out--it would require Harmonix to record a guitarist playing the song five times, from 50% slow to 90% slow (the Beatles themselves provide the 100% speed). Otherwise great game and lots of fun.
