rock band, anyone have it?

i have it for 360.

its just like guitar hero, but with drums and a mic. you can choose to play lead guitar or bass guitar as well.

whenever you miss a note, it will not play in the song. i dont know about playing your own beats, as i havent tried every mode yet, i just jumped into the world tour with 3 friends. i havent played it for ps3, but i imagine its the same.
